Martensitic stainless steel 13Cr-5Ni-2Mo Super 13Cr round bar, S41425 Flat bar, stock available, from steelmaking, hot forged, rolled, heat treated
TECHNICAL DATA SHEET - Super alloy 13Cr
MATERIAL CATEGORY: martensitic stainless steel 13Cr-5Ni-2Mo
PRODUCT DESCRIPTION
The alloy is usually produced by EAF, AOD, VOD 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 bright in the annealed condition.
Final heat treatment: quenched and tempered.

Super alloy 13Cr is a low carbon martensitic steel with high corrosion resistance.
This material is typically used in fully-setting equipment and environments contains Chlorides and CO2.
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.
