____________________________________________________Carbon Steel



Carbon steel is steel where the main interstitial alloying constituent is carbon in the range of 0.12-2.0%. Suitable for nominal pressure PN ≤ 32.0MPa, temperature -30-425 ℃ water, steam, air, hydrogen, ammonia, nitrogen and petroleum products, and other media.

_____________________________________________________Alloy Steel



Alloy steel is often subdivided into two groups: high alloy steels and low alloy steels. The difference between the two is defined somewhat arbitrarily. However, most agree that any steel that is alloyed with more than eight percent of its weight being other elements beside iron and carbon, is high alloy steel. 

Types High Tensile Steel, Case Hardening Steels and Steels specially developed for their nitriding properties.
Material 9CR-L80,13CR-L80,4130,4130M,4140,4145,4145M,4340,4330 V-MOD,8630MOD,C90,C110,L80,P110,Q125,T95



__________________________________________________Stainless Steel



Stainless steel does not readily corrode, rust or stain with water as ordinary steel does, but despite the name it is not fully stain-proof, most notably under low oxygen, high salinity, or poor circulation environments. It is also called corrosion-resistant steel or CRES when the alloy type and grade are not detailed, particularly in the aviation industry.

Types Stainless steel bar, stainless steel plate & sheet, stainless steel coil/strip
Material SS 304, 304L, 304H, 316, 316L, 316LN, 316Ti, 309, 310S, 317L, 321, 347, 409, 410, 420, 430, 446, 202 Etc.



__________________________________________________Black Steel



Black steel is a term given to steel pipe with a black oxide scale on the surface. This black oxide scale is formed when the pipe is forged and is typically sealed with a protective oil to prevent corrosion. Because of this oxide scale and protective film, black steel pipe requires little maintenance and is used for a wide variety of applications, including in water, steam, air and gas services. 

Types ERW black steel pipe
Material ASTM A-53 Grade A
Sizes 1/2"-2"
