Product Description
AISI 3115 15CrNi6 Seamless Steel Pipe
1: DIN 1.5919 Steel Introduction
15CrNi6/1.5919 is a low-alloy steel containing chromium and Nickel as strengthening elements.It has good mechanical property for highly strained parts and good toughness at core tensile strength of 900 - 1200 N/mm2. This material is generally used driving bevel gears, crown wheels, gears, shafts, bolts for automotive and gear components.
