440c Round Bar

We produce ASTM/ASME Grade 304, Grade 304L,304h, 316, 316L, 316H, 316TI, 321, 321H, 309S, 309H, 310S, 310H, 410S, 2205, 904L, 2507, 254, gh3030, 625, 253MA, S30815, 317L, Type 317, 316lN, 8020, 800, 800H, C276, S32304 and others special requirement stainless steel grade.

This grade is supposed to supply most hardness and wear resistance with stainless properties. 440C can be hardened to 60 HRC which is the best hardness of some other stainless-steel. 440C is usually used in bearing assemblies, cutlery, pump parts and textile equipment. 440C after heat treating is the able to attaining the very best strength.

It has optimum corrosion resistance within the hardened and tempered condition when tempered under 400oC. Polishing will further develop its corrosion resistance. Type 440C is a martensitic chrome steel that is able to buying, upon warmth therapy, the very best hardness of any type of corrosion resisting steels. It has its optimum corrosion resisting qualities in the hardened and tempered situation and is magnetic in all situations. 440C is a high carbon stainless designed to supply both stainless properties and most hardness.

Grade 309 or 310 filler rods will, nonetheless, present gentle welds, having excessive ductility. — Grade 440 stainless steels are full annealed at 850 to 900°C, followed by slow furnace-cooling at about 600°C and air-cooling.

• Grade 440C stainless-steel is a excessive carbon martensitic chrome steel.
• Compared to austenitic grades, 440C has average corrosion resistance, similar to 304.
• Type 440C is a martensitic stainless steel with excessive carbon and chromium content material.
• After heat treatment, it is able to attaining the very best strength, hardness and wear resistance of all stainless alloys.
• It has high power, average corrosion resistance, and good hardness and wear resistance.

However, grade 440C is more available than the opposite commonplace grades. Grade 440F, a free-machining type of grade 440 sequence, can also be available with a excessive carbon content much like that of grade 440C. Martensitic steel grades are high-hardness steels, often fabricated using methods that require hardening and tempering treatments. 17.00-18.00% Added only to excessive alloy tool steels, this improves hardenability, excessive wear resistance, toughness, and corrosion resistance.

Astm A240/ Asme Sa 240 Grade 440c Stainless Steel Sheet

The larger carbon content material in 440C yields a way more put on resistant knife blade. Stainless 440C is a excessive-carbon martensitic chrome steel.

Thickness Tolerance +.015″, Width Tolerance +.015″, Length Tolerance +.25″. Flatness Tolerance .001″ per Inch. 310 Stainless Steel – Austenitic warmth resistant grade with greater chromium and nickel for oxidation resistance past 2000°F. it is a hardenable stainless steel alloy, hardenable to a higher hardness than 420 collection stainless steels (that are only hardenable to 52 HRC!). 440A has good corrosion resistance, and is used in less expensive bearings and in harder surgical tools (uncommon).

Astm A240 Tp440c Stainless Steel Plate Physical Properties

Rolled Alloys provides thirteen-eight round bar in inventory and available online. Martensitic PH stainless with high energy, hardness, superior toughness and good corrosion resistance. Grade 440 stainless steels are heated at 1010 to 1065°C, then quenched in air or oil. Oil quenching is usually carried out for heavy sections. Following this course of, these steels are tempered at temperatures from a hundred and fifty to 370°C, to achieve a excessive hardness and improved mechanical properties.

We have thousands tons stock of stainless steel sheet and coil with various size and grade,mainly include austenitic stainless steel, martens stainless steel (including precipitation hardened stainless steel sheet & coil), ferritic stainless steel, and duplex stainless steel.

Characteristics of Stainless Steel Sheet and Plate:
