Product Description
Grade 440C is classified as a martensitic class of stainless steel. This steel grade contains a high content of carbon in its chemistry. This is why the 440C stainless steel round bar is referred to as a high carbon stainless steel alloy. Because of the higher content of carbon in its chemical composition, the martensitic 440Cc stainless steel welding rod exhibits properties such as high strength, and good hardness and wear resistance.
Unlike conventional stainless steels in the austenitic class, the corrosion resistance properties of 440C stainless steel rods are considered to be in the moderate range. However, for the properties, the most vital characteristic of the Stainless Steel 440C Round Bar is its yield and tensile strength. Compared to several austenitic stainless steels, which are ductile, the tensile strength of ASTM A479 UNS S44004 hex bar ranges between 760 MPa - 1970 MPa. And the yield strength at an offset of 0.200% is somewhere between 450 MPa - 1900 MPa. It is very difficult to weld this particular alloy since the JIS SUS 440C black bar is easily air hardened.
And so the material requires a pre-weld and a post-weld heat treatment for a duration of 6 hours to prevent the astm a276 type 440C flat bar from cracking. Because of its superior hardness and good mechanical strength, the applications of the AISI 440C threaded bar are suited to instrumentations as well as molds and dies. In order to improve the properties of the alloy, the ss 440C bright bar is given heat treatment. The practice of heat treatment improves properties such as the strength, hardness, and wear resistance of the DIN 1.4125 square bar.
