AISI3415 AMS6260E 655H13 15NiCr13 1.5752 Case Hardening Steel

Description

15NiCr13 is a remelted nickel chrome molybdenum case hardening steel produced by the PESR* (Pressurised ESR) method designed for components with high demand in toughness and core strength.

Application

Highly stressed components in automotive construction, and for general engineering purposes, e. g. gears, crankshafts, gearshafts.

Advantages

Good machinability (hobbing and turning).
Good dimensional stability.
Homogenous PESR structure suitable for the production of large components.
Improved polishability, photo-etchability and EDM due to higher purity.
Suitable for single and double hardening.
