High Carbon Spring Steel Wire
We produce high-performance high carbon spring steel wire with grades 72A, 72B, 82B, T9A and 65Mn, wire diameter ranging from 0.3mm to 10mm. Precise multi-pass cold drawing technology locks stable tensile indexes and uniform hardness for every high carbon spring steel wire.
High-Strength Performance Highlights
High carbon composition
Elevated carbon content greatly boosts the wire's overall hardness and tensile capacity after cold drawing.
Ultra-high tensile strength
Reaches 1800MPa–2800MPa based on wire diameter and material grade, supporting heavy-load elastic parts.
Powerful elastic recovery
High rigidity delivers strong rebound force suitable for mechanical components bearing large loads.
Excellent wear resistance
High hardness reduces surface abrasion for parts with frequent friction contact.
Temper & Surface Selections
Cold drawn, lead patented and oil tempered tempers are available. Surface treatments include bright finish, phosphating and lead coating to match different forming and service environments.
Application Scope
Applied to manufacture high-strength industrial springs, mattress springs, mechanical elastic components and steel wire ropes.
Precise Strength Control Technology
Baoding Zhongxin Spring Manufacturing Co., Ltd. accumulates rich experience in strength control of high carbon spring steel wire. We formulate exclusive drawing and heat treatment parameters for different materials and wire sizes to stabilize tensile strength within standard tolerance ranges. Real-time strength sampling inspection is implemented in every production procedure to adjust process parameters timely. Special strict quality standards are set for high-carbon wire to control raw material and finished product quality layer by layer. Stable strength consistency guarantees uniform elastic force and reliable load-bearing capacity of finished springs for downstream clients.
