Brinell, Rockwell and Vickers hardness indexes are commonly used to measure the hardness of stainless steel pipes. Stainless steel pipes can be divided into CR series (400 Series), Cr Ni series (300 Series), Cr Mn Ni series (200 Series) and precipitation hardening series (600 Series). 200 series - chromium nickel manganese austenitic stainless steel 300 series - chromium nickel austenitic stainless steel.

Surface Finish of our stainless steel
|
No.2B |
The surface brightness and flatness of No.2B is better than No.2D. then through a special surface treatment to improve its mechanical properties,No.2B could nearly satisfy comprehensive uses. |
|
No.3 |
Polished with abrasive belt of git#100-#200, have better brightness with discontinuous coarse stria, used as inner and external ornaments for building, electrical appliances and kitchen utensils etc. |
|
No.4 |
Polished with abrasive belt of grit #150-#180,have better brightness with discontinuous coarse stria, but thinner than No3, are used as bathtub buildings inner and external ornaments electrical appliances kitchen utensils and food processing equipment etc. |
|
HL |
Polished with abrasive belt of grit #150-#320 on the NO.4 finish and has continuous streaks, mainly used as buildings ornaments elevators, door of building, frontal plate etc. |
|
BA |
Cold rolled, bright annealed and skin-passed, the product have excellent brightness and good reflexivity like mirror, kitchen apparatus,ornament etc. |
|
8K |
The product have excellent brightness and prefer reflexivity can to be the mirror. |
Stainless steel pipes are divided into ordinary carbon steel pipes, high-quality carbon structural steel pipes, alloy structural pipes, alloy steel pipes, bearing steel pipes, stainless steel pipes, bimetallic composite pipes, coated and coated pipes to save precious metals and meet special requirements.
Stainless steel pipes have a wide variety, different uses, different technical requirements and different production methods. At present, the outer diameter range of steel pipes is 0.1-4500mm and the wall thickness range is 0.01-250mm.
Stainless steel pipe can be divided into seamless pipe and welded pipe according to the production mode. Seamless steel pipe can be divided into hot-rolled pipe, cold-rolled pipe, cold drawn pipe and extruded pipe. Cold drawing and cold rolling are the secondary processing of steel pipe; Welded pipe is divided into straight seam welded pipe and spiral welded pipe. There are various connection modes of stainless steel pipes. The common types of pipe fittings are compression type, compression type, union type, push type, push thread type, socket welding type, union flange connection, welding type and derivative series connection mode combining welding with traditional connection. According to the purpose, it can be divided into oil well pipe (casing, oil pipe and drill pipe), pipeline pipe, boiler pipe, mechanical structure pipe, hydraulic prop pipe, gas cylinder pipe, geological pipe, chemical pipe (high-pressure fertilizer pipe, petroleum cracking pipe) and marine pipe.
