1.4980 – Alloy A-286 is a precipitation hardening, austenitic stainless steel designed for use at elevated temperatures up to 700*C. It possesses high tensile strength, excellent creep strength and good corrosion resistance and if the hardness is <35HRC it is suitable for petrochemical applications use in H2S-containing environments in gas & generation production per NACE MR0103 / NACE MR01075.
Alloy A-286 is an alloy typically used under elevated temperatures and is a common material used for bolts, flanges and especially in petrochemical applications considering it’s resistance to H2S corrosion. Alloy A-286 is forged in three-stage process by first applying a solution annealing heat treatment, followed by ageing and stabilization / precipitation hardening to achieve the desired mechanical properties.
