Austenitic grades proffer superlative corrosion resistance properties. In comparison, Grade 301 has low chromium and nickel content. In close monitoring, both grades perform similarly in mild corrosion circumstances. But in aggravated conditions like high-temperature grade 304 has better performance than grade 301.

For, grade 310, high carbon content forms carbon carbides during welding, which caused chromium depletion from the surface. It makes it more prone to inter-granular corrosion.

Tensile strength

Due to high carbon content, grade 301 offers considerable tensile strength than grade 304.

Cost

Grade 304 is quite more expensive than grade 301. The higher concentration of chromium and nickel makes it pricey. Nickel is a commodity with a volatile price.

Applications

Grade 301 is majorly used in the production of kitchen equipment, trailers, springs, railways, automobiles, wheel covers, etc.

Grade 304 is used in food processing industries, kitchen appliances, architectural paneling, chemical containers, heat-exchangers, water filtration systems, etc.

Which is better? Grade 301 or 304?

In the first instance, grade 304 seems to be expensive. But long term usability with fewer maintenance issues can justify its relativity with another grade. That doesn’t mean grade 301 is not an asset. Grade 301 is an instant choice where the cost of the project is a major focus. Its applications can be installed in numerous indoor places.

Grade 304 is an ideal choice for high-temperature exposed applications and aggressive corrosive mediums.
