What is ams 5618?
AMS 5618 is a specification for 440C / 440 Stainless Steel Bars and Forgings, Consumable Electrode Vacuum Melted. 440C is a high carbon martensitic stainless steel that has slightly more carbon than 440A and 440B giving it the highest hardness of any martensitic stainless alloy.
WHAT IS 440C material?
Grade 440C stainless steel is a high carbon martensitic stainless steel. It has high strength, moderate corrosion resistance, and good hardness and wear resistance. Grade 440C is capable of attaining, after heat treatment, the highest strength, hardness and wear resistance of all the stainless alloys.

What is AMS5630?
AMS5630: Steel, Corrosion-Resistant, Bars, Wire, and Forgings, 17Cr – 0.52Mo (0.95 – 1.20C) (SAE 51440C) – SAE International.
What is AMS5639?
AMS5639: Steel, Corrosion-Resistant, Bars, Wire, Forgings, Tubing, and Rings, 19Cr – 10Ni, Solution Heat Treated – SAE International.
What is ASTM a276?
This specification covers hot-finished or cold-finished bars except bars for reforging. It includes rounds, squares, and hexagons, and hot-rolled or extruded shapes, such as angles, tees, and channels in the more commonly used types of stainless steels.
IS 440C a high carbon steel?
440C (UNS designation S44004) is a martensitic 400 series stainless steel, and is the highest carbon content from 400 stainless steel series. It is usually heat treated to reach hardness of 58–60 HRC. It is a bearing steel, and used in rolling contact stainless bearings, e.g. ball bearings and roller bearings.
How much carbon is in 440C steel?
440C stainless steels typically have a composition of 78 – 83.1% iron, 16 – 18% chromium, 1 – 1.2% carbon, 1% (max) silicon, 1% (max) manganese, 0.8% molybdenum, 0.04% phosphorus and 0.02% sulphur.
How hard can 440C get?
440C (UNS designation S44004) is a martensitic 400 series stainless steel, and is the highest carbon content from 400 stainless steel series. It is usually heat treated to reach hardness of 58–60 HRC.
What material is AMS 5645?
321 Stainless Steel
321 Stainless Steel – AMS 5510, AMS 5645 321 SS (UNS S32100) is a titanium stabilized austenitic stainless steel that features improved resistance to intergranular corrosion.
What is the difference between ASTM A276 and ASTM A479?
A479 specifically refers to use in boiler and pressure vessel applications. A276 specifically defers bars for reforging and free machining grades to other ASTM standards (A314 and A582/A582M) while A479 is silent on those items and they are presumed to not be covered.
What ASTM is stainless steel?
ASTM A666
ASTM A666 is the specification standard for how austenitic stainless steel is heated and cooled for various applications. It states that this metal needs to adhere to certain requirements regarding chemical composition and should be formed into a thin steel sheet, bar, plate, or thin metal strips.
What is the difference between AMS 5618 and AMS 440C?
AMS 5618 is typically used for anti-friction bearing components where resistance to both corrosion and wear is essential. 440C is capable of hardnesses in excess of 58 HRC after heat treatment. AMS 5630 is available in Bars, Wire and Forgings.
What is 440C stainless steel?
440C Stainless Steel is a high carbon chromium steel. In addition, 440C is martensitic. This grade is meant to provide maximum hardness and wear resistance with stainless properties. 440C can be hardened to 60 HRC which is the highest hardness of any other stainless steel. 440C is typically used in bearing assemblies, cutlery,…
What is the difference between AISI 400C and 440C?
AISI 400C is available in either standard melted (ams 5630) or vacuum melted (ams 5618) versions. AMS 5618 is typically used for anti-friction bearing components where resistance to both corrosion and wear is essential. 440C is capable of hardnesses in excess of 58 HRC after heat treatment. AMS 5630 is available in Bars, Wire and Forgings.
Is 440C available for order?
440C is available for order in round bar and mill quantities of sheet. 440C is also available in vac melt per AMS 5618. Looking for more information on 440C?
