TECHNICAL DATA SHEET - SA 336 Grade F11 Class 1

MATERIAL CATEGORY - Alloy Steel Forgings for Pressure and High-Temperature Parts.

MATERIAL SPECIFICATIONS - SA 336 / 336M -07

PRODUCT DESCRIPTION
F1 Alloy Steel 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. 20 ~ 180mm, plate, sheet

PRODUCT PROFILE & DIMENSIONS
Rod / round bar / disc (diameter): 5.5 ~ 850mm
Square bar & flat bar: 10 ~ 600mm
Plate & Sheet: cold & hot rolled / forged T 3.0 ~ 300 X W 10 ~ 1000 X L mm
