Ki sa ki se dezagregasyon tiyo asye?

Weathering steel, that is, atmospheric corrosion resistant steel, is a low alloy steel series between ordinary steel and stainless steel. Weathering steel is made of ordinary carbon steel with a small amount of corrosion resistant elements such as copper and nickel added. It has the characteristics of high-quality steel such as toughness, plasticity, forming, welding, abrasion, high temperature, and rezistans fatig; rezistans move tan li se 2 a 8 fwa sa yo ki an asye kabòn òdinè, ak pent li yo se 1 . 5 a 10 fwa sa yo ki an asye kabòn òdinè {{11} Ferovyèr, machin, pon, ak gwo fò tou won ki ekspoze a atmosfè a pou yon tan long . Li itilize pou fabrike resipyan, machin tren, lwil oliv, bilding pò, tribin pwodiksyon lwil, ak ekipman petwòl chimik ki gen idwojèn sulfure medya korozivite ak lòt pati estriktirèl.
