303 austenitic stainless steel is acid resistant stainless steel.To improve the performance of steel,more than 0.60% molybdenum is add in steel , so it can be ablative, easy cutting and corroded.
Production process :smelting, rolling, forging, drawing, annealing, twisted rope, weaving, cutting cutting, stamping, polishing, casting.
