316L Stainless Steel MIM Manufacturers

Grade 316L, the low carbon version of 316 and is immune from sensitisation (grain boundary carbide precipitation). Thus it is extensively used in heavy gauge welded components (over about 6mm) & medical industry. There is commonly no appreciable price difference between 316 and 316L stainless steel. 

316 Stainless steel easily than other iron-based metals, but it’s not literally “stainless”. Just like standard steel, stainless can get marked up by fingerprints and grease, develop discoloration, and eventually rust. The difference is resilience. Stainless steel can withstand much more time and abuse before showing signs of wear.

All steels have the same basic iron and carbon composition, but stainless steel also contains a healthy dose of chromium—the alloy that gives stainless steel its famous corrosion resistance.

Stainless steel  may be suitable for fresh water, but in higher chloride levels stainless steel 316  is preferable. is considered to be the strongest of 316L classifications and able to withstand corrosion longer.  The conditions in tidal river estuaries and seawater where higher chlorides, low flow rates and low oxygen levels can predominate may require higher molybdenum grade stainless steels such as a 6% molybdenum grade Care must also be taken to avoid bimetallic (galvanic) corrosion if combinations of dissimilar metals are to be used.

Properties are similar to those of Type 304 except that this alloy is somewhat stronger at elevated temperatures.

Advantages:

• 17-4 PH Stainless Steel provides excellent corrosion resistance and withstands corrosive attacks better than any of the standard stainless steels.
• The combination of high corrosion resistance and good mechanical strength made this 17-4 PH stainless steel to be used for marine applications.
• It is also used in other industries like petrochemical, petroleum, food processing industry and paper production industry.
