TECHNICAL DATA SHEET - 15H2M
Material category: 1.7Ni - 0.2Mo base alloy steel
Technical standards: ГОСT 4543 -1971
Available in stock: round bar diam. 20 ~ 100 mm
PRODUCT DESCRIPTION
The alloy 15H2M 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.
