Martensitic steel AISI 501 peeled round bar, plate, forge piece properties from steelmaking, hot forged / rolled, heat treated, cold worked
TECHNICAL DATA SHEET - AISI 501
MATERIAL CATEGORY: martensite type 5.0Cr - 0.5Mo
PRODUCT DESCRIPTION
AISI 501 is usually produced by AOD / 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 in the annealed condition.
Final heat treatment - quenched and tempered.

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.
TYPICAL APPLICATIONS
Chemical equipments.
Mechanical parts used in the condition of corrosion resistance.
Bolts, nuts, and pressure vessel.
