Alloy 20 daim hlau los yog alloy 20 tau tsim tshwj xeeb los fim sulfuric acid. Nws cov nickel, chromium, molybdenum thiab tooj liab tiers tag nrho muaj qhov zoo tshaj plaws trendy corrosion kuj. Confined carbon ntxiv rau columbium stabilization tso cai rau welded fabrications siv nyob rau hauv corrosive ib puag ncig, feem ntau tsis muab tso-weld kho cua sov. Ntawm 33% npib tsib xee, alloy 20 muaj tswv yim tiv thaiv chloride strain corrosion cracking. Cov hlau no feem ntau xaiv los daws cov teeb meem SCC, uas kuj tuaj yeem tshwm sim nrog 316L stainless.
