Stainless Steel Square Bar-430

Stainless Steel Square Bar-430

According to the production process, stainless steel rods can be divided into three types: hot rolling, forging and cold drawing. The specification of hot rolled stainless steel round bar is 5.5-250 mm. Among them: 5.5-25mm small stainless steel round bars are mostly supplied in bundles of straight strips, which are often used as steel bars, bolts and various mechanical parts; stainless steel round bars larger than 25mm are mainly used for the manufacture of mechanical parts or as seamless steel pipe billets .

430 stainless steel is a general-purpose steel with good corrosion resistance, better thermal conductivity than austenite, smaller thermal expansion coefficient than austenite, heat-resistant fatigue, adding stabilizing element titanium, and good mechanical properties of welds. 430 stainless steel is used for architectural decoration, fuel burner parts, household appliances, and home appliance parts. 430F is a steel grade with free cutting properties added to 430 steel, which is mainly used for automatic lathes, bolts and nuts. 430LX adds Ti or Nb to 430 steel, reduces C content, improves processing performance and welding performance, and is mainly used in hot water tanks, hot water supply systems, sanitary appliances, household durable appliances, bicycle flywheels, etc.
430 is a ferritic stainless steel, and 430 16Cr is a representative steel grade of ferritic steel, with good thermal expansion rate, excellent formability and oxidation resistance. Heat-resistant appliances, burners, home appliances, Class 2 tableware, kitchen sinks, exterior trim materials, bolts, nuts, CD rods, screens.

430 Characteristic machining technology

1D -- The surface has discontinuous granular shape, also known as fog surface.
Processing technology: hot rolling + annealing shot peening pickling + cold rolling + annealing pickling.
2D - A slightly silvery white colour.
Processing technology: hot rolling + annealing shot peening pickling + cold rolling + annealing pickling.
2B -- Silver white with better gloss and flatness than a 2D surface.
Processing technology: hot rolling + annealing shot peening pickling + cold rolling + annealing pickling + quenching and tempering rolling.
Ba - Excellent surface gloss, high reflectivity, like a mirror surface.
Processing technology: hot rolling + annealing shot peening pickling + cold rolling + annealing pickling + surface polishing + quenching and tempering rolling.
No.3 -- Good gloss, coarse grain surface.
Processing technology: polishing and tempering rolling for 2D or 2B with 100~120 abrasive materials (JIS R6002).
No.4 -- Good gloss, fine lines on the surface.
Processing process: polishing and tempering rolling for 2D or 2B with 150~180 abrasive materials (JIS R6002).
HL -- Silver grey with hair streaks.
Processing technology: 2D products or 2B products with appropriate granularity of abrasive materials for polishing the surface is a continuous abrasive grain.
MIRRO -- Specular.
Processing technology: 2D products or 2B products with appropriate granularity of the grinding material grinding and polishing to the mirror effect.
