dot  440C Stainless steel

 

440c_stainless_steel

440C Stainless Steel is a martensitic grade of stainless steel that provides very good wear resistance combined with moderate corrosion resistance in mild environments. 440C is heat treatable to RC 59. This grade is commonly used in cutlery and food processing applications.

440C Stainless steel is a type of modern steel and famous for its high corrosion resistant, wear resistance, strength and hardness qualities among all the stainless alloys, capable of attaining (after heat treatment) the highest hardness (60 HRC). It has good resistance to the atmosphere, fresh water and mild acids. It has best resistance in the hardened, tempered and passivated condition. It allows creating a smooth polished surface and Razor sharp edges. It is being used in cutting instruments, rolling element bearings, valve seats, high quality knife blades, surgical instruments, chisels, ball bearings and valve parts and most commonly used in the production of Cutting tools, including Haircutting Scissors, daggers and swords.

Grades 440A and 440B are identical except for slightly lower carbon contents (0.60 – 0.75% and 0.75 – 0.95% respectively), they attain lower hardness but slightly higher corrosion resistances. Although all three versions of this grade are standard grades, in practice 440C is more available than the A or B variants. Another alloy 440F (UNS S44020) also exists, with the same high carbon content as 440C.

Corrosion Resistance of 440C Stainless Steel:

440C stainless steel is characterized by good corrosion resistance in mild domestic and industrial environments, including fresh water, organic materials, mild acids, various petroleum products. 440C also provides extreme high strength, hardness and wear resistance when in the hardened and tempered condition.

Thermal Treatments:

  • Preheat: Optional preheat stage for unbalanced geometries or complex designs – 1100/1250F (590/675C), equalize, standard preheat stage – 1400/1500F (760/815C), equalize.
  • Austenize: 1850/1900F (1010/1020C), equalize, 30/45 minutes at temperature.
  • Quench: Air, positive pressure vacuum to below 125F (50C)(2 bar minimum). Interrupted oil to below 1000F (540C). Air cool to 150F (65C). Temper immediately.
  • Temper: 400/800F (205/425C), hold 2 hours at temperature, air cool. Temper twice. Avoid tempering between 800 and 1100F, due to a decrease in toughness and corrosion resistance.
  • Cryogenic Treating: Refrigeration treatments may improve long term dimensional stability by transforming retained austenite. Refrigeration treatments should generally be performed after the first temper, and must be followed by a temper

dot  Stainless Steel 304

 

stainless_steel_304

Stainless Steel 304/304L is of high quality. Stainless Steel 304 is a variation of the basic 18-8 grade, Type 302, with a higher chromium and lower carbon content. Lower carbon minimizes chromium carbide precipitation due to welding and its susceptibility to inter-granular corrosion. In many instances, it can be used in the ”as-welded“ condition, while Type 302 must be annealed in order to retain adequate corrosion resistance.

Type 304L is an extra low-carbon variation of Type 304 with a 0.03% maximum carbon content that eliminates carbide precipitation due to welding. As a result, this alloy can be used in the”as-welded“condition, even in severe corrosive conditions. It often eliminates the necessity of annealing weldments except for applications specifying stress relief. It has slightly lower mechanical properties than Type 304.

Typical Uses include architectural mouldings and trim, kitchen equipment, welded components of chemical, textile, paper, pharmaceutical and chemical industry processing equipment.

Available forms of Stainless Steel 304/304L:

Stainless Steel 304 is available in thicknesses from 0.01″ to 0.25″ (0.025 to 6.35 mm) max. and widths up to 48″ (1219 mm). For other thicknesses and widths, inquire.
