GJB 1951-94 Material Specification for Quality Structure Steel Bar for Aviation 16Cr2MnTiA Stock Available Round bar, Flat bar 16Cr2MnTiA Forgings
MATERIAL STANDARD DATASHEET - GJB 16Cr2MnTiA
MATERIAL CATEGORY - Specification for Quality Structure Steel Bars for Aviation.
MATERIAL CATEGORY - Specification for Quality Structure Steel Bars for Aviation.
PRODUCT DESCRIPTION
The alloy is usually produced by EAF + VD + LF / BEF / VIM 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. 10 ~ 380mm
PRODUCT PROFILE & DIMENSIONS
Round bar & Disc (diameter): 5.5mm to 850mm
Square bar / Flat bar: 6mm to 600mm
Length: Fixed length or random length or based on the customer's special requirements.
Plate & Sheet steel: T2.0 ~ 350mm X W10 ~ 1500mm 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.
Mechanical parts - connecting rod, bolt and nuts.
