430 Lect Stainless Steel Bar

430 stainless steel is a universal steel with good corrosion resistance, better thermal conductivity than austenite, smaller thermal expansion coefficient than austenite, heat resistance fatigue, adding stabilized element titanium, good mechanical properties at the weld. 430 stainless steel used for building decoration, fuel burner parts, household appliances, home appliance parts. 430F is 430 steel with free cutting properties, mainly used in automatic lathes, bolts and nuts. 430LX add Ti or Nb in 430 steel, reduce the C content, improve the processing performance and welding performance, mainly used in hot water tank, heating water system, sanitary appliances, household durable appliances, bicycle flywheel and so on.

It is also known as 18/0 or 18-0 because of its chromium content. Compared with 18/8 and 18/10, it contains slightly less chromium and the hardness is correspondingly reduced.

Product Details

430 stainless steel has the following states, the state is not the same, dirty and corrosion resistance is not the same.

NO.1, 1D, 2D, 2B, N0.4, HL, BA, Mirror, and various other surface treatment states.

1D- The surface is discontinuous and granular, also known as fog surface. Processing technology: hot rolling + annealing shot peening pickling + cold rolling + annealing pickling.

2D- slightly shiny silvery white. Processing technology: hot rolling + annealing shot peening pickling + cold rolling + annealing pickling.

2B- Silvery white with better gloss and flatness than 2D surfaces. Processing technology: hot rolling + annealing shot peening pickling + cold rolling + annealing pickling + tempering rolling.

BA- Excellent surface gloss, high reflectivity, like mirror surface. Processing technology: hot rolling + annealing shot peening pickling + cold rolling + annealing pickling + surface polishing + tempered rolling.

No.3- have good gloss, the surface is coarse grain. Processing technology: 2D products or 2B with 100~120 grinding materials (JIS R6002) polishing and tempering rolling.

No.4- Good gloss, fine lines on the surface. Processing technology: 2D products or 2B with 150~180 abrasive material (JIS R6002) polishing and tempering rolling.

HL- is silver-gray with streaks of hair. Processing technology: the 2D or 2B products are polished with appropriate abrasive materials to make the surface continuous grinding grain.

MIRRO- mirrors. Processing technology: 2D or 2B products with appropriate particle size grinding materials for grinding and polishing to mirror effect.
