Sachiya Steel International is one of the Leading Manufacturer And Exporter Of High Quality Stainless Steel 321 Tube to Male Fittings, which is available at best price. Stainless Steel 321 Tube Fittings has increased resistance to scaling and intergranular corrosion (versus 304 / 316 material) due mainly to its added titanium content. Titanium addition in Stainless Steel 321H Tube Fittings eliminates the formation of chromium carbides at the grain boundaries by tying up the carbon and nitrogen as titanium carbides or nitrides.
While processing only stainless tools like steel brushes in Stainless Steel 321 Compression Tube Fittings, pneumatic picks and so on are allowed, in order to not endanger the passivation. Stainless Steel 321H Compression Tube Fittings is similar to stainless steel 304, but with higher nickel content and stabilized with titanium. Welding should be carried out using Stainless Steel 321 Male Connector Fittings or similar electrodes or rods (depending upon application), where no pre heat or post heat is generally required.

Stainless Steel 321H Male Connector Fittings is subject to pitting and crevice corrosion in warm chloride environments, and to stress corrosion cracking above about 60 °C. Stainless Steel 321H Ferrule Fittings can be used in up to 10 % diluted solutions at elevated temperatures. Stainless Steel 321 Double Ferrule Fittings cannot be hardened by heat treatment, only by cold working, where it can also be easily welded and processed by standard shop fabrication practices.
