SPIROL manufactures Coiled Spring Pins out of 316 stainless steel to meet specific application requirements. Type 316 stainless steel is similar to 302/304 stainless steel with a slightly higher nickel content and the addition of molybdenum. The molybdenum content increases the chemical resistance of this alloy greatly. 316 exhibits superior pitting resistance against sea water, acetic acid vapors, chlorides, sodium and calcium brines, hypochlorite solutions, phosphoric acid, and the sulfite liquors and sulfurous acids used in the paper and pulp industry. This alloy is also austenitic, non-magnetic and non-hardenable using conventional methods. 316 stainless steel has better mechanical properties at elevated temperatures than 302/304 and offers excellent mechanical integrity at subzero temperatures. Typical applications for SPIROL's 316 Stainless Steel Coiled Pins include the following: marine, processing equipment, industrial, oil and gas and medical.

High elasticity and volume are the premises for an extremely good insulation effect Resistant against acid and caustic except phosphoric or hydrofluoric acid or highly concentrated caustics Does not content toxic substances or heavy metals Non flammable following DIN 4102 Product availability: Square, rectangular, round braid or round twisted reinforced with chrome steel wire Surface graphite impregnation on request for increasing compactness and nonstick effect Product contains approx. 20 % organic carrierfiber which decomposes at 200 °C.
