Introduction：
304 Stainless Steel Sheet is widely used, with good corrosion resistance, heat resistance, low temperature strength and mechanical properties; good thermal workability, such as stamping and bending, no heat treatment hardening (non-magnetic, service temperature - 196°C~800° C). Stainless steel plate with 304 quality is ideal for a variety of general purpose and light duty applications. It contains chromium and nickel, which help improve its water, moisture and oxidation resistance. Properties of 304 stainless steel plate include: rust and oxidation resistant, easy to form and fabricate, non-magnetizable and strong in addition to being commonly used in building and construction. Attractive to work with, 304 stainless steel is ideal for food and healthcare applications as it can withstand most oxidizing acids and some corrosive substances.

Application：
304 stainless steel is an austenitic, non-magnetic steel. The stainless steel that is utilized the most is this one. 304 stainless steel plate is a versatile, rust- and heat-resistant general-purpose steel. Kitchen sinks, backsplashes, food equipment, and plumbing components are just a few applications for 304 stainless steel sheet metal.
