303 is a free cutting stainless steel containing sulfur and selenium, respectively. Stainless steel 303 improves cutting performance and high temperature bonding.
Best suited for automatic lathes.
Bolts and nuts.
303 stainless steel is austenitic free cutting stainless wear-resistant acid steel. In order to improve the performance of the steel, no more than 0.60% molybdenum can be added to the steel. It has good ablation resistance and good cutting and burning resistance.
Corrosion resistance. Mechanical properties of 303 stainless steel after annealing to remove stress, tensile strength 515MPa, yield 205MPa, elongation 40%.
Standard hardness of stainless steel 303 HRB 90-100, HRC 20-25, note: HRB100 = HRC20
● Heat treatment specification and metallographic structure:
Heat treatment specification: solution 1010 ~ 1150℃ quick cooling.
Metallographic structure: The structure is characterized by austenitic type.
● Delivery state: Generally delivery in heat treatment state, the type of heat treatment is specified in the contract;
If not indicated, delivery shall be made without heat treatment.

303 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.
