What is EN 36C Case Hardening Steel Flat Bar?
EN 36C Case Hardening Steel Flat Bar is a nickel-chromium alloy steel designed specifically for case hardening processes. The alloying elements improve the steel’s strength, toughness, and resistance to wear. After carburizing and heat treatment, EN 36C steel develops a hardened outer layer while retaining a tough and ductile inner core, which helps components resist wear and mechanical stress. Due to its excellent fatigue strength and resistance to shock loading, EN 36C is widely used in heavy-duty engineering and industrial applications. The flat bar form is particularly suitable for structural components, machine parts, and engineering plates where dimensional stability and strength are essential. EN 36C Case Hardening Steel Flat Bar is available in bright and black conditions, depending on the required finishing and machining process. The product range generally varies from 32 mm to 510 mm in thickness and 65 mm to 1050 mm in width, with standard lengths ranging from 3 meter to 6 meters, though customized sizes and lengths can also be supplied based on specific industrial requirements.
