How To Bend 321h stainless steel flats?

Bending 321H stainless steel flats can be challenging, but with exacting process planning and the right tooling, it is doable! When working on bending these types of steel flats, it is important to consider the minimum degree that must be applied when bending. It is also crucial to select the appropriate tooling for optimal results. Proper material selection for flat stock and tooling contributes directly to results that exceed expectations, as does patience in clocking your set-up time. By following these steps keenly, one will have reliable results while successfully bending 321H stainless steel flats with minimal effort.

What are the available sizes of the grade 321 ss flat bar?

Grade 321 SS flat bars come in various sizes to suit any application. They range from 3/8" thick and 1-1/4" wide to bars measuring 4" thick and over 10" wide. As grade 321 is an austenitic alloy, it can be used in many high-temperature services, making these bars ideal for structures used in the aerospace and shipbuilding industries, as well as processing applications such as heat exchangers and food handling equipment. They are strong and resistant to corrosion and possess excellent weldability, meaning they can also be used in oil refineries and chemical plants. With their strength and versatility, grade 321 stainless steel flat bars offer many advantages at almost any size needed.
