3cr13 stainless steel, categorized under the Chinese GB standard, is a high-grade martensitic stainless steel recognized globally for its optimal balance between hardness, corrosion resistance, and mechanical strength. As a "Standard Cr13" series alloy, its chemical composition—primarily containing 12.0-14.0% Chromium and 0.26-0.35% Carbon—allows it to undergo significant hardening through heat treatment. Unlike austenitic steels (such as 304), 3cr13 is magnetic and achieves exceptional wear resistance after quenching and tempering, making it the material of choice for industrial cutting tools, mechanical components, and surgical apparatus.
After a rigorous heat treatment process (typically quenching at 920-980°C and oil cooling), 3cr13 round steel reaches a Rockwell hardness (HRC) of 50-54. This specific hardness range ensures that tools maintain a sharp edge while retaining enough toughness to resist brittle fracture under stress.
While martensitic steels are generally less corrosion-resistant than the 300-series, 3cr13 offers superior performance in "quenched and tempered" conditions. It successfully resists atmospheric corrosion, steam, fresh water, and certain organic acids, providing a cost-effective solution for environments requiring both hygiene and durability.
In the global procurement landscape, 3cr13 is often compared to ASTM 410 and 420. 3cr13 effectively bridges the gap, offering higher carbon content than 410 (providing better hardness) and similar performance to 420J1. For international buyers, sourcing 3cr13 from specialized Chinese factories often yields a 15-20% cost advantage without compromising the chemical integrity required for high-precision manufacturing.
Shandong Baimaoxing Iron and Steel Co., Ltd., situated in the heart of China's industrial metallurgy hub, represents the pinnacle of modern steel supply chains. The "China Advantage" in 3cr13 round steel production is not merely about price; it is about Information Gain through technological integration and logistical efficiency.
Our factories leverage a complete supply chain from raw ore processing to high-precision round bar drawing. This vertical integration ensures consistent batch-to-batch chemical composition and minimizes trace impurities.
Equipped with spectrometer analysis, ultrasonic flaw detection, and mechanical performance testing, we provide a full MTC (Material Test Certificate) that aligns with international standards such as ISO 9001:2015.
Located in Liaocheng, we utilize the "One Belt One Road" rail networks and proximity to major ports like Qingdao to offer global enterprises reduced lead times and competitive shipping rates.
Widely used in the Yangjiang (China) and Solingen (Germany) style cutlery industries. 3cr13 provides the perfect "click" and edge retention for professional kitchen knives and folding tactical tools.
Ideal for surgical scissors, hemostatic forceps, and dental tools where repeated sterilization is required, and high mechanical strength is non-negotiable.
Used in the production of valve stems, pump shafts, and nozzles. Its ability to withstand high friction and moderate heat makes it a staple for Tier-1 automotive suppliers.
About Us: Shandong Baimaoxing Iron and Steel Co., Ltd. is a large-scale steel supplier specializing in R&D, processing, and technical services. Our facility integrates scientific management models widely used in aerospace, military equipment, and precision machining.
