Description S42201 Flat bars, On stock S42201 Plate, Forgings S42201 Sheet machined, Ex-stock Technical specifications - ASTM A276. From Melting, ESR & VAR technique, Blooming, Hot forging, Hot rolling, Heat treatment, Straightening, Ultrasonic flaw detection test.
TURBINE BLADE STEEL DATASHEET - Grade UNS S42201
MATERIAL CATEGORY: Martensite type 13Cr-Ni-Mo-W-V
PRODUCT DESCRIPTION
The alloy is usually produced by AOD / EAF / VIM 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 annealed condition.
Final heat treatment - QT + stress relieved.
AVAILABILITY
Round bar / flat bar / strip / hollow bar / forgings / ring
Bright - peeled + polishing, centerless grinding
Forged - ring, tube, pipe casing, discs, shaft
PRODUCT PROFILE & DIMENSIONS
Round bar / Wire rod (Diameter): 5.5mm to 500mm
Square bar / Flat bar: 3mm to 550mm
Plate / Sheet steel / Steel strip: 0.1mm to 200mm
Width: 8mm to 1000mm
Length: random length or based on the customer's special requirement.
Forged steel shape: stepped shafts with flanks / discs /tubes /slugs /donuts /cubes /other different shapes based on OEM.

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 equipment.
Mechanical parts used in the condition of corrosion resistance.
Bolt and nut.
Pressure vessel.
