Que hàn Inox Nihonweld NSS-316L

I. APPLICATIONS:

Welding of AlSl31. Welding of dissimilar metals such as mild steel to stainless steel. Under-laying of hard surfacing.

II. DESCRIPTION:

NSS-316 is 18%Cr-12%Ni-2%Mo austenitic stainless steel electrode. For the addition of molybdenum and enough amount of nickel, it is excellent to corrosion made by anti-oxidiging acdis such as sulfuric acid and dilute sulfuric acid. And it also used for welding to heat resisting steels because of its good creep properties at high temperature.

III. INSTRUCTION FOR WELDING:

• Remove dirts such as oil and dust from the groove.
• Normally, preheat is not necessary.
• Keep the arc length as short as possible.
• Rebake the electrode at 200-250°C for about one hour before use.
