Product Description
DIN 17210 / 17Cr3 1.7016 Case-Hardening Steel
1: 17Cr3 Steel Introduction
17Cr3 is a chromium-based alloy structural steel known for its high strength, good hardenability, and excellent toughness, making it ideal for wear-resistant and high-stress applications such as shafts, gears, fasteners, and hydraulic components. Typically supplied in a quenched and tempered (Q&T) condition with a hardness of 28-32 HRC, it offers low quenching distortion and reliable performance in demanding mechanical and industrial environments.

6: Goods available in China
17Cr3 steel is available in China's market primarily as hot-rolled bars and plates, though inventory levels are generally modest due to its specialized applications. The material can be readily sourced from Chinese steel mills and distributors, with lead times varying based on product form and specifications. As a chromium alloy steel, 17Cr3 is commonly supplied in normalized or quenched and tempered conditions to meet various mechanical property requirements.
