Stainless Steel Square Bar-904L

Stainless Steel Square Bar-904L

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 .

Super austenitic stainless steel (904L stainless steel plate) is a highly alloyed austenitic stainless steel with very low carbon content. It has good corrosion resistance in dilute sulfuric acid and is designed for harsh environments. It has high chromium content and sufficient nickel content. The addition of copper makes it have strong acid resistance, especially high resistance to chloride crevice corrosion and stress corrosion cracking, and is not easy to appear pitting and cracking. The corrosion ability is slightly better than other steel grades, and it has good machinability and weldability, and can be used for pressure vessels.

904L 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.
