OTAI SPECIAL STEEL is 1.4112 stainless steel stockholders and suppliers from china. more than 25 years of experience in 1.4112 steel round bar, flat bar, and plate supply.

1.4112 stainless steel is a martensitic stainless steel grade that can be heat treated up to 57 – 60 HRC. This grade is written as 1.4112 or X90CrMoV18 according to EN norm and UNS S44003 according to UNS norm.

1.4112 material has a good capability of getting hardness. It contains ~%0.90 carbon element and because of high carbon, this grade is a really good grade for high hardness. But since it contains ~%0.90 carbon, its corrosion resistance is not soo good. This grade can be used for surgical equipment, drills that require corrosion resistance, and valves. 1.4112 is also used to make knives and this stainless steel grade is a good grade for high-hardness knives.

1.4112 steel properties as below:
