Nascent Pipe & Tubes is one of the prominent manufacturing houses of high quality Stainless Steel 310H Fasteners (Bolts / Nuts), which are usually regarded as the standard “marine grade stainless steel”, but is not resistant to warm sea water. Stainless Steel 310H Hex Head Bolts has good oxidation resistance in intermittent service to 870 Degree C and in continuous service to 925 Degree C.
Continuous use of Stainless Steel 310H Hex Head Nuts in the 425 Degree C – 860 Degree C range is not recommended if subsequent aqueous corrosion resistance is important. In many marine environments, Stainless Steel 310H Square Bolts does exhibit surface corrosion, where it is usually visible as brown staining.

Stainless Steel 310H Square Nuts, with its higher carbon content has application at elevated temperatures, as does stabilised Alloy 316Ti. The molybdenum gives Stainless Steel 310H Eye Bolts better overall corrosion resistant properties than SS 304 Pipes, particularly higher resistance to pitting and crevice corrosion in chloride environments. Stainless Steel 310H Eye Nuts has excellent forming and welding characteristics.

The austenitic structure of Stainless Steel 310H U-Bolts also gives excellent toughness, even down to cryogenic temperatures. Stainless Steel 310H Lock Nuts is readily braked or roll formed into a variety of parts for applications in the architectural, transportation and industrial fields. Stainless Steel 310H T-Bolts are highly engineered to offer a superior Alloy of high temperature corrosion resistance, toughness, heat resistance and strength and for the most demanding applications.
