and the front weld is protected by argon slag and alloy elements.Standard classification - classification: national standard GB industry standard Yb local standard enterprise standard qcb- classification: product standard packaging standard basic standard - standard level (divided into three levels): y level: international advanced level I level: international general level H level: domestic advanced level - national standard: stainless steel bar (level I) gb- stainless welding disc Park (level H)Delgado,The selection of stainless steel plate shall consider the operating conditions, such as manual operation or automatic operation, the performance and type of hot press, and the quality requirements for materials, such as hardness, gloss, etc. Economic accounting should also be considered. Each time the steel plate is newly polished, it is required to produce a number of decorative plates with slow quality.Model & mdash; Commonly used precipitation hardening stainless steel model, usually also called -; %Cr,%Ni.Gidole,Austenitic stainless steel austenitic stainless steel is developed to overcome the lack of corrosion resistance and brittleness of martensitic stainless steel. The basic composition is crl% and Ni%, which is referred to as - steel for short. Its characteristic is that the carbon content is less than .%, and the single-phase austenite structure is obtained by the combination of Cr and Ni.The back is blocked with blocking plate for ventilation protection; Only soluble paper or the combination of soluble paper and blocking plate is used for blocking ventilation protection; Use flux cored wire for backing TIG welding. Series & mdash; Martensitic precipitation hardening stainless steel.

After molten steel casting, stainless steel pipe fittings generally adopt the same vertical, vertical bending or arc continuous caster as carbon steel. The refined molten steel is poured into the ladle, the ladle to be poured is transferred above the tundish mouth through the rotary table, and then the molten steel is tundish through the long nozzle. The molten steel in tundish enters the mold through the submerged nozzle for forming, condensation and continuous downward movement.Surface feature surface feature manufacturing method summary application silver white matte hot rolled to the specified thickness, and then annealed and descaled. A rough and matte surface does not need surface gloss. Silver white cold rolled heat treatment and pickling D products are used for applications with lax surface requirements. Generally, the gloss of deep drawing materials is stronger than that of D treatment, After finishing a light cold rolling with polishing roller, the general material Ba is as bright as a mirror. There is no standard, but it is usually the surface processing of bright annealing, and the surface reflectance is very high. For building materials, ~ # (unit) abrasive belt is used for kitchen coarse grinding to grind building materials, The polishing surface obtained by grinding with ~ # abrasive belt in the middle of the kitchen is the same as that obtained by fine grinding. The polishing surface is polished with # abrasive belt. The ultra-fine grinding in the kitchen is polished with # abrasive belt. The luster is similar to that of Ba. It is generally used for grinding with # polishing wheel. It is used for construction. It is specialized in stainless steel plate, stainless steel coil and stainless steel belt, Stainless steel pipe quality assurance. New and old customers are welcome to consult during the preferential activities. HL hair line grinding in the kitchen is carried out by grinding materials with appropriate particle size for hair line grinding ( ~ #). There are many buildings and building materials close to mirror grinding. # rotary polishing wheel is used for grinding for art, mirror grinding for decoration mirror grinding for mirror, and polishing wheel is used for grinding reflector, For decoration, according to the purpose, bridge steel plate, boiler steel plate, armored steel plate, automobile steel plate, roof steel plate, structural steel plate, electrical steel plate (silicon steel sheet), spring steel plate, special solar plate (Hairui special steel) are common Japanese brands in other steel plates for ordinary and mechanical structures.At low temperature, ferritic stainless steel pipe has low-temperature brittleness like carbon steel, but austenitic steel does not. Therefore, ferritic or martensitic stainless steel produces low-temperature brittleness, high purification process can be considered. With the help of C and N level it is necessary to pay special attention when using at low temperature. As a way to improve the impact toughness of ferritic series stainless steel, the embrittlement temperature is in the range of - ℃ to - ℃Quality risk,Deformation strengthening of austenitic stainless steel stainless steel has good cold deformation performance. It can be cold drawn into very thin steel wire and cold rolled into very thin steel strip or steel pipe. After a large amount of deformation, the strength of the steel is greatly improved, especially when rolling in the subzero temperature zone. The tensile strength can reach more than MPa. This is because in addition to the cold hardening effect, there are also superimposed Deformation induced M transition.Therefore,DelgadoStainless steel strip,Delgado202 stainless steel plate, there are requirements for the service environment of stainless steel, and it is necessary to remove dust frequently and keep it clean and dry.The operators are mainly plumbers and argon arc welders, with the cooperation of other types of work, and the argon arc welder shall have the certificate issued by relevant departments.

After molten steel casting, stainless steel pipe fittings generally adopt the same vertical, vertical bending or arc continuous caster as carbon steel. The refined molten steel is poured into the ladle, the ladle to be poured is transferred above the tundish mouth through the rotary table, and then the molten steel is tundish through the long nozzle. The molten steel in tundish enters the mold through the submerged nozzle for forming, condensation and continuous downward movement.Installation conditions, it can be said to be unique in metals, and its development continues. In order to make stainless steel more neutral in traditional applications, existing types have been improved, and new stainless steel is being developed to meet the strict requirements of advanced architectural applications. Due to the continuous improvement of production efficiency and quality, stainless steel has become one of the cost-effective materials selected by architects. Stainless steel integrates performance, appearance and use characteristics, so stainless steel will still be one of the best building materials in the world.This kind of steel pipe can be divided into stainless steel seamless steel pipe and stainless steel welded steel pipe (slotted pipe). According to different manufacturing processes, cold drawing and cold rolling. According to the section shape, it can be divided into circular pipe and special-shaped pipe. Circular steel pipe is widely used, but there are also some square, rectangular, semicircular, hexagonal, equilateral triangle Octagonal and other special-shaped stainless steel pipes.The welding of stainless steel pipe is usually composed of backing welding filling welding and cover welding. Backing welding of stainless steel pipe is a key link in stainless steel pipe welding, which is not only related to the quality of engineeringDelgado,The corrosion resistance is the same, and the strength is better because the carbon content is relatively high.Rockwell hardness the Rockwell hardness test of stainless steel pipe is the same as Brinell hardness test. The difference is that it measures the depth of indentation. Rockwell hardness test is widely used at present, and HRC is second only to Brinell hardness Hb in steel pipe standards. Rockwell hardness can be used to measure metal materials from very soft to very hard, which makes up for the disadvantage of Brinell method, It is simpler than Brinell method and can read the hardness value directly from the dial of the hardness machine. However, due to its small indentation, the hardness value is not as accurate as Brinell method.Application fields: chemical industry construction industry.
