DC Engineering is the manufacturer, supplier, and stockist of stainless steel  304H bolts. These bolts are enriched with high strength and flexibility. Stainless steel 304 is an advanced grade with extraordinary properties and characteristics. Grade 304 is made from austenitic steel; hence it is also called an austenitic grade. Stainless steel  304 grade has magnetic properties. These stainless steel  304L Bolts are enriched with other great qualities and features. 

Grade 304 is manufactured using an excellent combination of tensile elements such as manganese, chromium, and nickel. Stainless steel 304 Bolts also includes silicon, phosphorus, and carbon in its composition. 

Stainless steel bolts are commonly used for joining two or more objects together. Grade 304L Bolts provides excellent protection from other harmful chemical reactions which can cause extreme damage to the instrument or the grade. It delivers extreme flexibility and durability in high as well as low temperatures. It can easily withstand constant sulfur and chloride attacks.
