20Cr-38Ni-2Mo-3Cu Austenitic steel N08020 Round bar, flat bar, plate N08020 ESR refined, Hot forging, Hot rolling, Heat treatment, Straightening, 100% Ultrasonic flaw detection test.
MATERIAL TECHNICAL DATASHEET - UNS N08020
MATERIAL CATEGORY - 20Cr-38Ni-2Mo-3Cu Austenitic steel
PRODUCT DESCRIPTION
The alloy is usually produced by AOD / VOD / EAF followed by electroslag refining (ESR) / VAR if necessary for special purpose. Bars and, where applicable, forgings are subjected to ultrasonic examination based on the different levels according to the buyers' requirements.
Bars are usually supplied black/bright in the softened condition.
Final heat treatment - solution treatment / QT

HEAT TREATMENT PRACTICE
Heat treatment is only suitable for specific grades of stainless steel. When heat treating a stainless the hardening temperatures, including rate of heating, cooling and soaking times will vary due to several factors such as the shape and size of each component. Other considerations during the heat treatment process include the type of furnace, quenching medium and work piece transfer facilities. Please consult with the heat treatment provider for whole guidance on heat treatment of stainless steel grades. We are delighted to help to work with you the special heat treatment based on your special requirements.
