1.4303 / DIN X4CrNi18-12 – AISI 305 – UNS S30500

1.4303 is actually a higher alloyed version of 1.4306, meaning it has slightly higher nickel content and is therefore more corrosion resistant. The higher nickel content of this steel results in a more stable austenite phase that makes the steel particularly suitable for cold forming.

1.4303, which has an average mechanical property, has very good malleability, excellent weldability, and poor machinability.

It is resistant to calcification up to about 600 ° C. Suitable for cryogenic applications. It can be cold formed easily. Used in automotive industry, chemical industry, food and beverage industry, mechanical engineering, decoration products and kitchenware, electronic equipment, screw manufacturing, petrochemical industry.

1.4303 is resistant to corrosion in most natural water and urban and rural atmospheres provided that its chloride and salt content is low. This grade stainless steel is not seawater resistant and therefore should not be used in any seawater application. As with 1.4306, it is not suitable for use in swimming pools or swimming pool environments. Resistance to degradation of acids is also limited by low concentrations and low temperatures.
