    en.wikipedia.org/wiki/AL-6XN

    AL-6XN (UNS designation N08367) is a type of weldable stainless steel that consist of an alloy of nickel (24%), chromium (22%) and molybdenum (6.3%) with other trace elements such as nitrogen. The high nickel and molybdenum contents of the AL-6XN alloy give it good resistance to chloride stress- corrosion cracking.

  4. Austenitic stainless steel - Wikipedia

    en.wikipedia.org/wiki/Austenitic_stainless_steel

    In 200 series stainless steels the structure is obtained by adding manganese and nitrogen, with a small amount of nickel content, making 200 series a cost-effective nickel-chromium austenitic type stainless steel. 300 series stainless steels are the larger subgroup. The most common austenitic stainless steel and most common of all stainless ...

    The energy from the impact plasticizes the materials, forming a weld, even though only a limited amount of heat is generated. The process is commonly used for welding dissimilar materials, including bonding aluminum to carbon steel in ship hulls and stainless steel or titanium to carbon steel in petrochemical pressure vessels.

  7. Shielding gas - Wikipedia

    en.wikipedia.org/wiki/Shielding_gas

    Argon with 25–35% helium and 1–2% CO 2 provides high productivity and good welds on austenitic stainless steels. Can be used for joining stainless steel to carbon steel. Argon-CO 2 with 1–2% hydrogen provides a reducing atmosphere that lowers amount of oxide on the weld surface, improves wetting and penetration. Good for austenitic ...
