Sachiya Steel International is One Of The Leading Manufacturer And Exporter Of High Quality Stainless Steel 904L Bolts And Nuts, which is a popular and highly machinable, along with lower cost martensitic free machining stainless steel. These Stainless Steel 904L Hex Head Bolts offers resistance to fresh water, acids, alkalis, and air; however it is less resistance to corrosion than austenitic steels. Our Stainless Steel 904L Hex Head Nuts also has the highest level of machinability of all stainless steels, and is available in various forms including highly tempered, hardened, and unhardened.
All hot – or cold – worked parts of these Stainless Steel 904L Square Bolts should be annealed and rapidly cooled in order to restore the best balance of properties. Carbide tools in Stainless Steel 904L Square Nuts should have smaller angles than high – speed tools and operating speeds can be higher. After 100 hours in petroleum coke, four other materials were completely penetrated by carburization; whereas specimens of these Stainless Steel 904L Eye Nuts showed no carburization at all.
Useful Properties for Aircraft and Furnace Parts – Stainless Steel 904L Eye Bolts is recommended especially for use in furnace applications because it has unusual resistance to oxidizing, reducing, and neutral atmospheres. The uncommon resistance to oxidation of these Stainless Steel 904L T-Bolts, combined with exceptional heat resistance and fabricability, make this steel a widely sought – after blend in a number of industries.
