Stainless Steel 440C Round Bars

Sankalp Alloys Overseas is one of the prime and renowned manufacturers, suppliers, exporters, and stockists of STAINLESS STEEL 440C ROUND BARS. This alloy features high resistivity in pitting and crevice-corrosive environments. Moreover, it performs superior in corrosive media like nitric acids, acetic acids, phosphoric acids, and chloride-containing environments. Our fabrication team manufactures SS 440C Round Bars per the prescribed national and international guidelines.

Manufacturers and suppliers also refer to this grade as the UNS designation alloy S44004. JIS SUS 440C black bar comes from the martensitic class of stainless steel. This alloy also possesses properties of the 400 series. Of all the 400 stainless steel series, the chemistry of the 440C stainless steel round bar contains the highest percentage of carbon content. The 440Cc stainless steel welding rod typically locks in the hardness between 58 HRC – 60 HRC right after it undergoes a heat treatment procedure. Manufacturers often subject alloy 440C to an oil-quenching kind of treatment.

Oil quenching is done to the ASTM A479 UNS S44004 hex bar to maximize its hardness properties. Heat treatment not only increases its hardness but the mechanical strength and wear resistance of the grade ASTM A276 type 440C flat bar also greatly boosts. One of the peculiarities of this alloy grade is that once it has been hardened, the AISI 440C threaded bar can hold a sharp edge and fight corrosion.

Controls on the mirror finish can be attained with a procedure as simple as polishing. Contra austenitic grades, 440C stainless steel rods are moderate resistance corrosion material compared to alloy 304. Even though this grade of stainless steel is hardenable through the use of a heat treatment procedure, machining is preferred on the DIN 1.4125 square bar in an annealed condition. This is so because it is easily machined in an annealed condition because the SS 440C bright bar tends to be very difficult once the alloy has been hardened.
