What is Stainless Steel 440C Round Bars?

Metcore Alloys is among the well-established manufacturers, suppliers, exporters, and stockists of Stainless Steel 440C Round Bars. These high-carbon martensitic stainless steels are also called UNS S44004 or JIS SUS 440C black bars and have much in common with every other alloy from the 400 series. In the category, the lethal series has stainless steel round bar 440C as the one with the highest carbon content.

Due to the heat treatment, the 440C stainless steel welding rod is found to reach hardness within the range of 58 HRC to 60 HRC. Manufacturers usually perform oil quenching on the ASTM A479 UNS S44004 hex bar in order to raise its mechanical strength, as well as increase its wear resistance and hardness capacity. The AISI 440C threaded bar has demonstrated that it holds an edge sharp and has provided fairly good resistance to corrosion under hardened conditions. This alloy grade is also able to support a near-mirror finish with simple polishing-a further reason why it is very suitable for applications where aesthetics and performance go together.

Compared to the corrosion resistance offered from austenitic grades like 304, the rods offer a fair amount of corrosion resistance, but at the same time, there will be an improvement in hardness. For example, the flat bar ASTM A276 Type 440C will be pretty difficult to machine once it is heat-treated because of its hardness; hence, machining is always performed in the annealed state of processing.

Our SS 440C bright bars are manufactured for high-demanding engineering applications and are further processed into different tolerance levels, machining allowances, and surface finishes. Further, the bars conform to national and international standards, which makes them highly qualified for various industry requirements. We are one of the leading stockiest, and we store a great inventory of stainless steel round bars in various standards, specifications, and custom dimension.

At Metcore Alloys, we are mechanized with advanced machinery and equipment for fabrication of 440C round bars as per set quality standards. The logistic service used ensures the supply of products in a harmless condition, having on-time delivery facilities that would meet the requirements of different industries across different sectors. Metcore Alloys is dedicated to providing premium-grade AISI 440C Stainless Steel Round Bars, manufactured from materials that have gone through rigorous testing and certification processes.
