Introduction

Grade 202 stainless steel is a type of Cr-Ni-Mn stainless with similar properties to A240/SUS 302 stainless steel. The toughness of grade 202 at low temperatures is excellent.

It is one of the most widely used precipitation hardening grades, and possesses good corrosion resistance, toughness, high harness, and strength.

The following datasheet provides an overview of grade 202 B stainless steel.

Chemical Composition

The chemical composition of grade 202 stainless steel is outlined in the following table.

Mechanical Properties

The mechanical properties of grade 202 stainless steel are displayed in the following table.

Other Designations

Equivalent materials to grade 202 stainless steel are given below:

Manufacturing Process

The machinability of grade 202 stainless steel produces long, gummy chips. Machining can also be performed in the annealed condition. For heat treatment, the material has to be soaked at 1038°C (1900°F) for 30 min and cooled below 16°C (60°F) for full martensite transformation. The material can be welded by common fusion and resistance methods; however, this steel should not be joined using oxyacetylene welding method. The recommended filler metal is AWS E/ER630. Forging can be done by pre-soaking for 1 h at 1177°C (2150°F). Forging below 1010°C (1850°F) is not advisable.

The grade 202 steel can be made into plates, sheets, and coils to be used in the following:

• Restaurant equipment
• Cooking utensils
• Sinks
• Automotive trim
• Architectural applications such as windows and doors
• Railway cars
• Trailers
• Hose clamps.
