Things To Know About Stainless Steel

The 300 series designation comprises many diverse compositions of metal steel bolts and nuts and attachments (303, 304, 304L, 305, 316, 321, 347, 316S31, 316Letc.) Nevertheless, the common factors among them are:

  • Their carbon material is usually held to a maximum of 0.08percent
  • They (generally) have 18% chromium
  • They (generally) have 8 percent nickel
  • they’re non-magnetic
  • They can’t be hardened by heat treatment

The second most popular sort of stainless steel bolt and nuts or screws or fasteners, after Type 304, is Type 316. In Type 316 stainless steel nut and bolt & washers SS 316 Nut and bolt, the chromium content is reduced from 18% to 16%, but the nickel content is increased to 10% and 2% molybdenum is added into the mix. This shift in the chromium/nickel ratio and the inclusion of the molybdenum increases the resistance to chlorides.

The current use of 316S31 grade nut and bolt & washers in marine software and sewage plants and off shore applications from the west has improved the performance of the bolt, and it has given a longer life to the products life cycle.

There’s not any doubt from the fact that wrapped thread bolts are better in terms of strength and precision than cutting threads. But it’s also a fact that nobody generates common sized of bolts. In manufacturing environment it is much cheaper to roll up the threads than cutting them and produce much better results also.
