  • What is the difference between 304 and 316 stainless steel?

    The main difference is corrosion resistance.
    Stainless Steel 316 contains molybdenum, which provides better resistance to chemicals and saltwater environments compared to 304.

    316 is ideal for marine and medical applications, while 304 is more cost-effective for general use.

  • What is the best stainless steel for machining?

    Stainless Steel 303 is typically the easiest to machine due to its improved machinability.
    However, Stainless Steel 304 and 316 are more commonly used because they offer better corrosion resistance and overall performance.

    Our engineers can recommend the best material based on your specific requirements.
