2:- What is the difference between various type of steels grades. (SS 304, SS304L , SS 316 , SS 316L etc) which one is most costlier?

Question

Accepted Answer

Different steel grades have varying properties and uses. SS316L is the most expensive.

SS304 and SS304L are commonly used in food processing and chemical industries.
SS316 and SS316L have higher corrosion resistance and are used in marine and pharmaceutical industries.
SS316L is the most expensive due to its higher nickel and molybdenum content.
The choice of steel grade depends on the specific application and required properties.

Accepted Answer

The main differences between stainless steel grades are their chemical composition and the cost, which is determined by the alloys used:
SS 304
This grade typically has an 8–10.5% nickel content. It's a good choice when low cost is more important than corrosion resistance.
SS 316
This grade has a higher nickel content (10–14%) and also contains 2–3% molybdenum. The molybdenum and nickel content make it more expensive than SS 304, and it's also more resistant to corrosion. SS 316 is often used in industrial and commercial settings, and in applications such as marine, pharmaceutical, and chemical processing. 
 
Here are some other differences between stainless steel grades:
SS 316L: This grade is stronger and more durable than SS 304, and it's also more resistant to corrosion. It's often used in semiconductor manufacturing.
Malleability: SS 316 is less malleable than SS 304.
