Vacuum melted implantable stainless steel, extremely clean chemical composition, excellent biocompatibility, corrosion resistance and reliable fatigue performance.
Easy machining martensitic stainless steel ideal for precision medical parts, small tolerances, high surface finish and moderate corrosion resistance.
High hardness martensitic stainless steel used for surgical instruments, has excellent polishing performance and good edge retention, low cost.
Implant Grade 316LVM for Human Contact
SparkX provides 316LVM produced using vacuum melting and remelting processes, and it has extremely low inclusion and gas content, ideal for trauma plates, screws and other temporary or permanent implants. We control chemistry windows and segregation to meet typical ASTM F138 / ISO 5832-1 requirements or your OEM specifications. SparkX provides bars and wires that are supplied with bright, defect-free surfaces and EN 10204 3.1 certificates.
so your quality and regulatory teams can trace every furnace and batch of products.
416 & 420j2 for Sharp, Reliable Instruments
As you know, medical devices typically need to maintain stability under high fatigue conditions and require good ductility, strength, and corrosion resistance. For some medical devices, such as surgical scissors, scalpels, forceps, and dental instruments, SparkX provides martensitic stainless steel 416 and 420J2 and tight control of sulfur content and hardness range. 416 is easy to machine, and it’s very suitable for complex handles and instrument bodies, and it has excellent cutting performance. 420J2, after heat treatment and polishing, has high hardness and edge retention. We guarantee the straightness, decarburization layer depth, and grain size of the rods from the source, and help you to reduce grinding and polishing costs, while still having a mirror finish.
Services & Documentation
Medical customers don’t just need the steel; they also need stability and complete documentation. SparkX has designed dedicated process routes for 316LVM, 416, and 420J2, and tightly controlled furnace batch numbers, dedicated inspection plans, and retained samples for each shipment. We can also provide chemical analysis, mechanical properties, micro-cleanliness, corrosion tests, and RoHS/REACH statements in one package, so your product quality is perfectly guaranteed. Packing, labeling, and palletizing are designed for clean room or machining workshop use, so your material can be directly cut, ground, and polished.
Generally, 316LVM is mainly used for trauma and orthopedic implants such as plates, screws, and wires that contact bone or tissue. But 416 and 420J2 are usually used for surgical instruments, dental tools, and medical device components that are not inside the human body. Please tell us your device and contact type, and we will recommend the most suitable grades and routes.
For 316LVM, 416, and 420J2, we can provide trial orders from 1 heat and limited tonnage, and it depends on the size and shape. So you can test your process before volume production.
Each batch of medical steel from SparkX is all EN 10204 3.1, and if you need, we can also provide 3.2 with third-party inspection. We can also run more comprehensive tests, such as microscopic cleanliness, intergranular corrosion, pitting in chloride media, hardness after your heat treatment profile, and even specific inclusion rating methods agreed with your QA team.
