440C Round Bar is a grade of 440 stainless steel. ASTM A276 Type 440C Bar stock has the highest carbon content which makes them suitable for most wear-resistant environments. Due to high carbon these 440C Steel Bar can be used in high-temperature applications.
440C Steel Bar are manufactured in Round, Square, Flat, and Small Diameter Rod. 440C Stainless Steel manufacturers produce these bars according to ASTM A276 and F899 specification. The 440C Stainless Steel Round Bar is mainly used in automotive, aerospace, and industrial machinery. Aerospace sector consumes AMS 5630 Bar stock instead of ASTM A276. AMS full form is Aerospace Material Specification and follows SAE International standard.
ASTM A276 440C material also known for high corrosion resistance quality and hardness. AISI 440C Round Bar and Rods are widely used to produce parts for Pump, Valve components, Medical instruments, Ball bearings and races.
Furthermore, 440C Stainless Steel Bar can be used in critical applications even in the high stress and wear conditions. SS 440C bars are very durable and perform for a longer period in industrial and automotive sectors. Heat treated 440C Stainless Bar has the highest tensile strength between 1900-2050 MPa which can be used to manufacture Knives, bearings, and other industrial wear parts. Cold finish 440C Round Bars are known for the tighter dimensional and superior finish. The surface roughness of 440C Flat Bar and Rounds are measured by RMS (Root Mean Square).
440C Steel Bar is also referred to as SUS440C in Japan, DIN X105CrMo17 in Germany, EN 1.4125 in Europe, AFNOR Z100CD17 in France, and UNI X102CrMo17 in Italy. 440C Stainless Steel Bar can be produced up to 200mm (as rolled) and up to 400mm diameter (as forged).
