38crmoal Round Bar High Strength Tool Steel
38CrMoAl Alloy Steel round bar
Customer need 26 tons 1.8509 alloy steel, Otai Steel engineer suggest 38CrMoAl to them .There is rare 1.8509 stock material in China ,all of Chinese steel mill production 38CrMoAl instead of 1.8509.
Customer try to order 1.8550 /1.8507 /1.8519 instead of 1.8509 alloy steel round bar .and our engineer update the folow chemical composition as below to customer for reference . and customer Choose 38CrMoAl finally .
