ASTM A511/511M - 12 Standard specification for seamless stainless steel mechanical tubing MT 403 round bar, flat bar, plate, forgings MT 403 stock available, hardening heat treated
TECHNICAL DATA SHEET - MT 403
Material specifications: ASTM A511 / 511M - 12
Material category: martensitic type 12.0Cr - 0.1C iron base steel
Official test certificate: issued by TUV - SGS - CNAS
Stock available: round bar, sheet, plate, flat bar.
PRODUCT DESCRIPTION
MT 403 is usually produced by EAF, AOD followed by electro-slag 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 in the annealed, peeled condition.
Final heat treatment: quenched and tempered, + SRA.
