303 / 1.4305 Stainless Steel Coil

1. 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% of molybdenum can be added to the steel to resist ablation.

2. Mechanical properties of 303 stainless steel after annealing and stress relief, the tensile strength is 515MPa, the yield is 205MPa, and the elongation is 40%.

3. The standard hardness of stainless steel 303 is HRB90-100, HRC20-25, note: HRB100=HRC22.9.

4. 303 is a free-cutting stainless steel that contains sulfur and selenium respectively, and is used in occasions where free-cutting and high surface finish are mainly required.

5. 303 stainless steel improves cutting performance and high temperature resistance bonding performance. Most suitable for automatic lathes, bolts and nuts.

303 stainless steel is an austenitic free-cutting stainless and wear-resistant acid steel containing sulfur and selenium respectively. It is used for occasions that require easy cutting and high surface finish. 304 steel is a universal stainless steel material with strong corrosion resistance, and also has good corrosion resistance to alkaline solutions and most organic and inorganic acids.

What is the difference between 303 stainless steel and 304 stainless steel?

The difference between 303 stainless steel and 304 is in function, composition, and function. 303 stainless steel is an easy-to-cut material, contains more elements such as sulfur and carbon, and is often used for machining parts.

1. Different functions
303 stainless steel and 304 have different functions. 303 stainless steel is a relatively easy-to-cut material with a smooth surface and high finish, while 304 stainless steel is a versatile material with poor finish but a wider range of applications.

2. Different ingredients
The composition of 303 stainless steel is different from that of 304. 303 stainless steel contains more sulfur and carbon elements, and is often used in occasions with higher finishes, while 304 stainless steel contains less sulfur and carbon elements and is resistant to high temperatures. It is a food-grade stainless steel material.

3. Different roles
The role of 303 stainless steel is different from that of 304. 303 stainless steel is resistant to burning and can be used to make metal parts such as bolts, nuts, screws, and 304 stainless steel can withstand high temperatures of 800 degrees, and is often used in food, medical, home decoration and other fields.
