UGI® 4062 Bright Bars
UGI® 4062 Bright Bars introduction
UGI® 4062 is an austenitic-ferritic or duplex stainless steel with a minimum content of 22 % chromium and 2 % nickel, specially designed as an economically interesting alternative to the grades of the types 1.4301/1.4307 (AISI 304/304L) and 1.4310 (AISI 302/301).
This grade has high mechanical properties and its corrosion resistance is comparable to that of grades 1.4301/1.4310.
Impact strength data: This grade is partially ferritic and has a ductile-brittle transition temperature which restricts its use in the case of large size bars at low temperature.
After ""solution annealing"" in the temperature range 980 °C – 1,050 °C, with water, oil or air cooling, UGI® 4062 is composed of ferrite and austenite in comparable quantities. As a result, it is partially ferromagnetic (it can be ""magnetised"").
During strong cold deformation (wire drawing, etc.), one part of the austenite is transformed into martensite and UGI® 4062 becomes more magnetic.
It is not advised to use UGI® 4062 above 300 °C in order to keep all its properties (refer to hot working paragraph).
Equivalent material: DIN 1.4062, EN 1.4062, UNS S32202, AFNOR X2CrNiN22-2
