What is Stainless Steel 321/321H Scrap?
Stainless Steel 321/321H scrap is composed primarily of iron, chromium and nickel with small amounts of titanium added for stability during welding or high temperature service to protect from the formation of chromium carbides during welding processes or high temperature use. Machinability generally meets expectations although due to higher strength/hardness values it may prove more challenging compared with some other stainless grades, with appropriate tools and cutting conditions this material can still be machined efficiently for various applications.
Stainless Steel 321/321H scrap offers outstanding corrosion resistance in most environments, especially acidic, chloride-containing environments and high-temperature settings due to its high content of chromium and nickel which forms an oxide layer on its surface and protects it from further oxidation. As a result, its suitable use includes chemical processing equipment as well as automotive exhaust systems whose environments might present hazards that corrosive elements may aggravate.
Weldability is one of the main features of Stainless Steel 321/321H scrap, as it can easily be joined using standard methods of welding such as arc welding, resistance welding and gas tungsten arc welding (GTAW). Titanium addition helps prevent carbide precipitation at grain boundaries to minimize intergranular corrosion risks after welding; making Stainless Steel 321/321H an attractive material choice for fabrication companies and manufacturers in industries requiring welded components like aerospace, petrochemical and power generation.
Stainless Steel 321/321H scrap has many diverse applications, spanning structural components in aircraft to exhaust systems in automobiles. Due to its combination of strength, corrosion resistance and heat resistance properties it finds use across industries from aircraft construction to car exhausts systems - among them are turbine engine components, heat exchangers in chemical plants and furnace parts used for heating industrial heating systems - just a few specific examples being its ability to stand up against harsh environmental conditions and remain functional at any given moment in their processes.
Stainless Steel 321/321H scrap finds widespread applications across many industries where high temperature and corrosion resistance is necessary, such as aerospace engineering, chemical processing equipment, thermal processing equipment, heat exchangers and automotive applications. Due to its versatility and robustness it makes an attractive option in demanding environments where reliability and durability are at their forefront.
