In order to control the quality of 316H bolts, the material of 316H bars is melted by ESR+VIR or VIM+ESR+VAR and is produced as the standard of ASTM B462 and ASTM B473

316H is susceptible to carbide precipitation when exposed in the temperature range of 800° - 1500°F and therefore is susceptible to intergranular corrosion in the as-welded condition.
