Hastelloy B2 Springs

A Spring is an elastic object used to store mechanical energy, designed to absorb and release force (or "spring back") when compressed, extended, or twisted. In critical industrial applications, springs must maintain their mechanical properties while resisting extremely corrosive media. Hastelloy B2 (UNS N10665) is an ideal material for springs in reducing environments, offering exceptional resistance to non-oxidizing acids, including concentrated hydrochloric acid (HCl) and sulfuric acid, even at elevated temperatures. The high molybdenum content ensures high localized corrosion resistance, crucial for the surface integrity of coiled wire. Zeron Fastners is a reliable manufacturer and supplier of these high-performance nickel alloy springs, providing reliable load-bearing and sealing components for the most aggressive chemical, pharmaceutical, and furnace environments.
