Grade F6nm


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:
High corrosion resistance
High toughness and resistance
Temperature resistance
High workability, including machining, stamping, fabricating and welding
Smooth surface finish that can be easily clean

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.

The hot deformation behavior of F6NM chrome steel was investigated by sizzling take a look at in a Gleeble-1500D -mechanical simulator. The move strain-stress curves were obtained and the corresponding metallographic statement of this steel under different deformation conditions was also carried out. This steel exhibited dynamic recrystallization in the temperature of 1273–1473 K and the strain price range of 0.

Astm A182 F6nm

These alloy additives have restricted the need to increase the carbon content within the grade – a given focus is similar to stainless austenitic grade. The presence of ~ 4% – though not at a high stage, considerably increases the steel’s resistance to quite a few corrosive environments – secondary mechanical properties.

F6NM is a low–carbon martensitic stainless-steel with basic corrosion resistance, good power, good toughness and a lot better weldability than most martensitic of chrome steel. F6NM is martensitic grade of chrome steel with a number of important enhancements.

  • F6NM is martensitic grade of stainless steel with several necessary enhancements.
  • F6NM is a low–carbon martensitic stainless-steel with primary corrosion resistance, good strength, good toughness and much better weldability than most martensitic grades of chrome steel.
  • The low carbon gives much improved weldability and together with the nickel produces excellent toughness.
  • The molybdenum addition gives an improved corrosion resistance.

Cold Rolled,Hot Rolled Stainless steel Plate and sheets

The weldability and corrosion resistance of ASTM A182 are additionally glorious, being extensively used in the manufacture of Valve Bodies, Flanges, Seats, Gates, and Tubulars. UNS S41500 steel is air hardening, with little hazard of thick sections cracking throughout heat remedy.

However, the inner oxide movie is Cr-rich, and two oxide films, whose thicknesses enhance with rising exposure time. The oxide movie reduces the corrosion habits because the outer oxide movie has many crack and pores.

The molybdenum addition offers an improved corrosion resistance. The low carbon gives much improved weldability and along with the nickel produces excellent toughness. 17/4 PH is a precipitation hardening martensitic chrome steel, containing Copper. In the answer treated and doubled aged condition it has turn out to be the preferred alloy for Stems, Shafts, and so on, and is used extensively in valve internals.

The activation vitality for decent deformation was decided to be 457. 91 kJ/mol, and the new deformation equations had been additionally established. The move instability zone was determined and could be divided into two areas.
