Stainless Steel 321 Plate

What is Stainless Steel 321 Sheet?

Designed to combat the failure of mechanical and corrosion resistance properties, the ASTM A240 321 SS sheets were intended to be used in the chromium carbide precipitation range.

At this range, the temperature could range anywhere between 1800 – 1500°F and un-stabilized alloys, for instance, grade 304 are subject to intergranular attack. However, with the modification in its chemistry, the SS Werkstoff No 1.4541 sheet has superior performance on occurrence of the chromium carbide precipitation range. The yield strength of SA 240 Gr 321 SS is about 280 Mpa, with its melting point falling between the temperature range of 2550 – 2635°F.The SUS 321 plates are available in standard thickness from 4.8 mm up to 101.6 mm.

What is ASTM A240 Grade 321 Plate?

Grade 321 Stainless Steel plate produced according to the ASTM A240 specification are meant to be used for pressure vessels and other applications. Apart from plates, the ASTM A240 Type 321 strip, coil and sheet are to conform to the mechanical and chemical requirements.

What is SS 321H Sheet?

Stainless steel grade UNS S 32109 sheet is the modified higher carbon containing version of alloy 321. Alloy 321H sheets were developed with the intention of being used at elevated temperature settings. This being said, the AISI 321/321H UNS S32100 / S32109 shim stock offers not only enhanced resistance to creep but also higher tensile strength properties at temperatures above 1000°F.
