304 Stainless Steel (S30400)
The most versatile and widely used chromium-nickel (18/8) austenitic stainless steel.
Stainless steel types 1.4301 and 1.4307 are also known as grades 304 and 304L respectively. Type 304 is the most versatile and widely used stainless steel. It is still sometimes referred to by its old name 18/8 which is derived from the nominal composition of type 304 being 18% chromium and 8% nickel.
304 төрөл stainless steel is an austenitic grade that can be severely deep drawn. This property has resulted in 304 being the dominant grade used in applications like sinks and saucepans.
Type 304L is the low carbon version of 304. It is used in heavy gauge components for improved weldability. Some products such as plate and pipe may be available as “dual certified” material that meets the criteria for both 304 and 304L.
304H, a high carbon content variant, is also available for use at high temperatures.
304 stainless steel is the most widely used austenitic stainless steel, known for its excellent corrosion resistance, good mechanical properties, and versatile fabrication capabilities. It is often used in industrial, architectural, and household applications.
