Sachiya Steel International is One Of The Leading Manufacturer And Exporter Of High Quality Stainless Steel 347H Nuts And Bolts, which are achieved by adding other alloying elements, such as manganese, nickel, chrome, titanium and molybdenum to the basic mix. Stainless Steel 347H Hex Head Bolts contain a mass fraction of at least 10.5 % chromium and a maximum of 1.2 % carbon. Other important alloying elements of Stainless Steel 347H Hex Head Nuts include Ni, Mo, Cu and many others, depending on the desired properties and application.

Stainless Steel 347H Nuts

 Stainless Steel 347H Nuts

Usually steels that do not form rust in the natural environment are named as Stainless Steel 347H Square Bolts. The most important group within Stainless Steel 347H Square Nuts are the austenitic stainless steels, which contain a minimum of 18 % chromium and 8 % nickel. Austenitic Stainless Steel 347H Eye Bolts are not magnetizable, where the most important element besides iron is carbon.

Due to the austenitic structure, Stainless Steel 347H Eye Nuts show a good ductility, and at low temperatures are very cold formable and show good weldability. The properties of Stainless Steel 347H U-Bolts can be widely influenced by alloying elements and heat treatment conditions. The carbon is essential in Stainless Steel 347H Lock Nuts which are to be hardened by quenching and tempering. The hardness of Stainless Steel 347H T-Bolts, as with all steel groups, is directly related to the amount of carbon alloyed.
