TECHNICAL DATA SHEET - 35CrMo1A & PCrMo
MATERIAL CATEGORY - Specification for Alloy Structure Steel Bar for Artillery Parts,
MATERIAL CATEGORY - Specification for Alloy Structure Steel Bar for Artillery Parts,
MATERIAL SPECIFICATIONS - GJB 1220A - 2008.
PRODUCT DESCRIPTION
Alloy is usually produced by EAF + VD + LF / BEF followed by electroslag refining (ESR) if necessary for special purpose. Bars and, where applicable, forgings are subjected to ultrasonic examination based on the different level according to the buyers' requirements.
Bars are usually supplied bright in the annealed condition, or bright annealing specially.
Final heat treatment - Quenched and tempered.
Stock available: round bar diam. 25 ~ 200 mm, ESR ingot, forging blank.
PRODUCT PROFILE & DIMENSIONS
Rod & round bar & disc (diameter): 5.5 ~ 850mm
Square bar & flat bar: T6 ~ 400 X W 15 ~ 600 X Lmm
Length: Fixed length or random length or based on the customer's special requirement.
Plate & Sheet steel: T0.5 - 200 X W10 - 1000 X Lmm
TYPICAL APPLICATIONS
Alloy structural steels are widely used in the filed of ship, vehicle, airplane, guided missile, weapons, railway, bridges, pressure vessel, machine tools, mechanical components with a bigger sectional size and so on.
