What material is en1.4112 ?
EN 1.4112 is a high-hardness, wear-resistant, martensitic stainless steel, also known by its UNS number S44003, AISI 440B, and X90CrMoV18, featuring additions of chromium, molybdenum, and vanadium for excellent edge retention and polishability, making it ideal for knives, surgical tools, and high-performance bearings.
What material is 1.4112 equivalent to?
1.4112 material is a high-carbon martensitic stainless steel equivalent to AISI 440B, known by its European designation X90CrMoV18 and UNS S44003, offering high hardness, wear resistance, and good corrosion resistance, commonly used for cutting tools, surgical instruments, and molds.
What is the chemical composition of 1.4112?
1.4112 (also known as AISI 440B or X90CrMoV18) is a high-carbon martensitic stainless steel with primary elements of Chromium (17-19%) and Carbon (0.85-0.95%), plus Molybdenum and Vanadium for enhanced hardness.

Is 1.4112 stainless steel magnetic?
Yes, 1.4112 stainless steel is magnetic because it is a martensitic chromium steel. Martensitic grades of stainless steel, such as 1.4112 (also known as AISI 440B), are known for being magnetic due to their composition and crystal structure, unlike austenitic stainless steels which are generally non-magnetic.
What is the density of 1.4112 stainless steel?
The density of 1.4112 stainless steel (also known as X90CrMoV18 or AISI 440B) is typically around 7.7 to 7.85 g/cm³, with most sources citing 7.7 g/cm³ or 7.7 kg/dm³ as standard, though slight variations can occur based on the specific manufacturer and heat treatment.
What is the hardness of 1.4112 stainless steel?
Stainless steel turning milling1.4112 stainless steel (also known as AISI 440B or X90CrMoV18) is a hardenable martensitic steel, capable of achieving high hardness, typically ranging from 54 to 60 HRC (Rockwell Hardness C Scale) after heat treatment, with common working hardness between 53-58 HRC, while its annealed state is a maximum of 265 HB (Brinell).
What are the differences between 1.4112 and 1.4125 stainless steel?
1.4112 (AISI 440B) and 1.4125 (AISI 440C) are both high-carbon martensitic stainless steels used for cutting applications, but 1.4125 has a higher carbon content, resulting in higher hardness and wear resistance, while 1.4112 contains added vanadium, providing a better balance of hardness and toughness.
