Lamina ferrea in China
Lamina ferrea in China
Stainless Steel 304 the most late used stainless steel gradus.Chromium-nickel austeniticum est chalybem immaculatum cum contento carbonii relative humili et paulo altius chromium et nickel quam AISI species 301 et 302. Gradus 304 valde ductile est cum in condicione annealed.Habet proprietates temperaturas bene elevatas necnon duritiem bonam ad temperaturas humilis.Ad glutino bene convenit et ubi operis effecti gravioribus formis corrosionis resistere debet.
