Sachiya Steel International is one of the Leading Manufacturer And Exporter of Stainless Steel 321 Flanges, which has oxidation resistant to 1600 ° F. Stainless Steel 321 Flanges is developed to provide an 18-8 type alloy with improved inter-granular-corrosion resistance. Stainless Steel 321H Flanges is not subject to weld decay (inter-granular corrosion) when exposed to mildly corrosive environments. Stainless Steel 321 Slip On Raised Flanges is a titanium stabilized chromium-nickel austenitic stainless steel with good strength and excellent corrosion resistance, as supplied in the annealed condition.
Stainless Steel 321 Blind Raised Flanges is an excellent choice for various applications ranging from oil refinery equipment to automotive exhaust systems. Stainless Steel 321 Weld Neck Flanges can be readily formed and drawn, however, higher pressures are required and more spring-back is encountered than for carbon steel and ferrite stainless steels. Stress Relief – Heat this Stainless Steel 321 Socket Weld Flanges up to 700 ° C for 1 to 2 hours and air cool.

Stainless Steel 321 Threaded Flanges contains 18 % chromium, 8 % nickel and a substantial addition of titanium. Stainless Steel 321 Spectacle Blind Flanges has comparable corrosion resistance and machinability to Stainless Steel 304. Stainless Steel 321 Lap Joint Flanges is not suitable for work at temperatures below 1700 ° F (927 ° C). Titanium is added to the composition of Stainless Steel 321H Ring joint Type Flanges to suppress grain boundary chromium carbide precipitation and reduce susceptibility to inter-granular corrosion.

Sachiya Steel International is one of the Leading Manufacturer And Exporter Of a wide range of Stainless Steel 321 Round Bar, which has high carbon (.04 – 10) for better high temperature creep properties.
If subsequently used in service at room temperature while some slight precipitation of chromium carbide can occur in Stainless Steel 321 Round Bars over an extended period this will generally have little effect on corrosion resistance.
Stainless Steel 321H Round Bars provides excellent resistance to oxidation and corrosion and possesses good creep strength.Stainless Steel 321 Square Bars performs well in the 425 – 900 °C range, and particularly where subsequent aqueous corrosive conditions are present.
Stainless Steel 321H Flat Bars is utilized in chloride or fluoride free caustic solutions at moderate temperatures.
Stainless Steel 321 Threaded Bars was developed for use in the chromium carbide precipitation range of 1800 – 1500°F (427 – 816°C) where un-stabilized alloys such as 304 are subject to intergranular attack.Stainless Steel 321 Round Bar | Stainless Steel 321 Round Bar | Stainless Steel 321 Round Bar | Stainless Steel 321 Round Bar | Stainless Steel 321 Round Bar | Stainless Steel 321 Round Bar | Stainless Steel 321 Round Bar | Stainless Steel 321 Round Bar | Stainless Steel 321 Round Bar | Stainless Steel 321 Round Bar | Stainless Steel 321 Round BarPickling of the previously brushed seam area in Stainless Steel 321H Hollow Bars is carried out by dipping and spraying, however, often pickling pastes or solutions are used, where after pickling a careful flushing with water has to be done.
Stainless Steel 321 Hexagonal Bars has excellent corrosion resistance in a wide variety of corrosive media, along with high creep & stress rupture properties.
