430 v 304 stainless steel: the difference between bright annealed plate?

 

Chemical composition:

430 stainless steel contains about 17% chromium and 0.12% carbon, while 304 stainless steel contains about 18% chromium and 0.08% carbon.

Physical properties:

430 stainless steel is harder and more brittle than 304 stainless steel, but has better thermal conductivity and mechanical properties.

 

Corrosion resistance:

430 stainless steel contains 16%-18% chromium and no nickel, and its corrosion resistance is worse than 304.

304 stainless steel contains more chromium and nickel metals, has better corrosion resistance, and is suitable for a variety of corrosive environments.

 

Mechanical properties:

430 stainless steel has high strength and hardness, but relatively poor toughness.

304 stainless steel is not only corrosion-resistant, but also has high mechanical properties and toughness, and is easy to process, weld and form.

 

Price factors:

430 stainless steel has low manufacturing costs and is relatively cheap because it contains no or only a very small amount of nickel.

304 stainless steel contains a high nickel content, and its manufacturing cost and price are relatively high. ‌

‌

Application areas‌:

430 stainless steel is suitable for architectural decoration, home appliance parts and other fields.

304 stainless steel is widely used in food, medicine, chemical industry, construction, home appliances and other fields.
