440C is a 400 series stainless-steel, and is the highest carbon content from 400 stainless-steel series. It is a bearing steel, and used in rolling contact stainless bearings, e.g. ball and roller bearings. Otai steel may provide your prime very best quality AISI 440C chrome steel for your completely different software use, regardless of massive amount or small.

However, if welding is important, it ought to be preheated to 260°C (500°F) and post weld anneal handled at °C ( °F) for 6 h followed by slowly cooling within the furnace to forestall cracking. To get hold of mechanical properties within the weld similar to these in the base metal, welding consumables of like composition must be thought-about. AISI 440C stainless steel is a martensitic chrome steel formulated for primary forming into wrought merchandise.

 

• Small AISI 440C steel sections may be air cooled and quite large sections oil quenched for maximum through hardness.
• Among wrought stainless steels, the composition of AISI 440C stainless steel is notable for containing a relatively high amount of carbon (C).
• Grade 440C stainless steel is able to attaining, after warmth remedy, the highest power, hardness and wear resistance of all the stainless alloys.
• SS 440A, 440B and 440C chrome steel are AISI and ASTM normal excessive carbon high chromium martensitic stainless-steel, SS440 has excessive power, good hardness, corrosion resistance, put on resistance and excessive temperature dimensional stability.

Otherwise Unclassified Properties

AISI grade 440C chrome steel is pre-heated at 760°C (1400°F). It is then slowly cooled at room temperature and totally annealed. Because of 440C SS high carbon content material it machines somewhat like high-speed steel. Because chips are tough and stringy, chip curlers and breakers are important. Z100 CD 17 0.95/ 1.2 1.0 max 1.zero max 0.015 S max sixteen.zero/ 18.zero 0.eight max – – AISI 400C is a high carbon chromium metal is designed to supply stainless-steel properties with maximum hardness.

440C has the very best strength, hardness, and wear resistance of all of the commonplace 440-collection stainless alloys with high carbon content and reasonable corrosion resistance. Stainless 440C metal can be tempered by soaking at 148°C (300°F). Steel 440c hardness at approximately Rockwell C 60 will be obtained. To take away peak stresses and yet retain most hardness, temper at least one hour at 300/350ºF (149/177ºC).

Grade 440C stainless-steel could be machined within the annealed condition. Chip breakers can be utilized to handle tough and stringy chips. The mechanical properties of grade 440C chrome steel are displayed within the following desk. The following table exhibits the bodily properties of grade 440C stainless-steel.

SS 440A, 440B and 440C stainless steel are AISI and ASTM commonplace high carbon excessive chromium martensitic stainless-steel, SS440 has high power, good hardness, corrosion resistance, wear resistance and excessive temperature dimensional stability. For AISI 440 stainless steel datasheet, warmth remedy and equivalent chart, please see the tables beneath. Among wrought stainless steels, the composition of AISI 440C stainless-steel is notable for containing a relatively excessive quantity of carbon (C).
