They offer extensive ranges of characteristics such as good weldability, high toughness, and ease of fabrications. 321 and 321H are austenitic alloys made from suitable raw materials and are always appreciated by our clients. They are composed of Nickel, Chromium, and Titanium like other alloys; additionally, they also have silicon and carbon to improve their performance. They also bear strong corrosive resistance against crevice and pitting environments.
Nickel-Chromium-based 321 and 321H Grades are used extensively in many applications. SS 321 Fasteners are commonly used in industries like Petrochemical Industries, Oil and Gas Industries, Chemical Industries, Heating & Tubing systems, Nuclear Power Plant, Heat exchangers, Power generations and Paper and Pulp Industries.
This grade is known for its excellent characteristics and properties. Stainless steel 321 fasteners are commonly used for joining and fitting two or more objects together.
