Most austenitic stainless steel weldments do not require postweld heat treatment. For those that do, the heat treatment temperature should reflect the particular concern that is being addressed. The necessity for any type of heat treatment of austenitic chromium-nickel steel weldments depends largely on the service conditions encountered.

5/7/2013· Recently, a manufacturer embarked on a project to help minimize its post heat treatment machining costs. The company is a tooling manufacturer that designs and supplies round dies made of 440°C stainless steel in sizes ranging from 50mm (2") diameter x 12.6 mm (½") thick to 200 mm (8") diameter x 25 mm (1") thick.
Get priceStainless steel is one of the most widely used alloys in metal casting — prized for its strength, hardness, and resistance to corrosion. But unlike other metals, the end of the casting process does not necessarily mean the product or component is market-ready. Heat treatment after stainless steel casting is often required to achieve the desired qualities of the finished product.

AISI 410 stainless steel is one of the most commonly used martensitic stainless steels. It contains about 12% Cr and therefore provides moderate corrosion resistance. Unlike austenite such as AISI 304 and AISI 316, martensite such as grade 410 is magnetic and can be hardened by heat treatment like carbon steel and low alloy steel. SS410 has ...

Get priceStainless steels may be divided into four groups to distinguish their response to heat treatments. The ferritic, austenitic and martensitic grades are described in Section 4.2. The precipitation hardening grades, designated with a PH suffix (e.g.15-5 PH) constitute a group which, unlike the other three, achieves both high strength and corrosion resistance.

Heat Treating Stainless Steel. Heat treating, a process that is used to harden or soften metals by heating and cooling them until they achieve their desired point of hardness, is often performed on stainless steel. In this metal, the structure and composition of the grains, or crystallites, determines its overall mechanical qualities.

Stainless steels have become versatile because of combination of following properties: 1. Good Corrosion and Oxidation Resistance: A fresh surface of stainless steel immediately reacts with the oxidising medium to form the protective (Cr 2 O 3) film which stops further reaction.Thus, the steels are resistant to corrosion and oxidation in an oxidising atmosphere.
