At our company, we’re all about crafting high-quality 17-4PH stainless steel tube for guidewire production that helps doctors navigate the trickiest blood vessels with precision and confidence. These tubes aren’t just metal—they’re the backbone of guidewires that make minimally invasive procedures like angioplasty and stenting possible, saving lives one vessel at a time. We focus on strength, flexibility, and reliability to deliver guidewires that perform flawlessly in high-stakes vascular interventions.
Let’s get into what makes our 17-4PH stainless steel tube for guidewire production a cut above. This precipitation-hardening alloy is a powerhouse, with 15-17.5% chromium for solid corrosion resistance, 3-5% nickel for toughness, 3-5% copper, and 0.15-0.45% niobium for boosted strength. With carbon below 0.07%, it meets ASTM A564 standards, perfect for medical-grade applications. We produce these tubes in diameters from 0.2mm to 3mm, with walls as thin as 0.05mm, ideal for guidewires that need to snake through tiny vessels. Our heat-treatment process dials in tensile strengths up to 1380 MPa, ensuring guidewires can flex and twist without breaking.

Precision is our thing. We cold-draw tubes to tolerances of ±0.005mm, ensuring they fit perfectly into guidewire assemblies. Electropolishing creates a Ra <0.2µm finish, reducing friction and enhancing biocompatibility for smooth vessel navigation. We test for fatigue resistance, simulating thousands of bends to mimic real-world catheter insertions, ensuring durability. While slightly magnetic, our tubes are optimized for minimal interference in imaging, keeping procedures safe. We also offer custom coatings, like hydrophilic layers, to improve lubricity, making guidewires glide through vessels with ease.
The guidewires market is booming, valued at USD 2.5 billion in 2025 and projected to hit USD 4.1 billion by 2032 at a 5.6% CAGR. Cardiovascular diseases are driving this growth—over 900 million people globally face heart issues, fueled by diabetes, obesity, and aging populations. Minimally invasive procedures, like percutaneous coronary interventions (PCI), are now standard, with over 3 million guidewires used annually. Our high-quality 17-4PH stainless steel tube for guidewire production is built for this, offering the strength for torque control and the flexibility to navigate tortuous vessels.
