Frequently Asked Questions
316LVM is vacuum melted, which significantly reduces non-metallic inclusions and increases purity, reducing the risk of ionic contamination in high-purity gas systems.
EP removes the surface layer to create a mirror-like finish, reducing surface roughness (Ra) and eliminating microscopic crevices where particles and contaminants can lodge.
For ultra-aggressive chemistries like concentrated HCl, Titanium Grade 2 or specific Nickel-based alloys are recommended due to their superior corrosion resistance.
We provide full Mill Test Certificates (MTC) and track every piece of tubing via Heat Numbers, ensuring a complete audit trail from the mill to the fab.
Duplex 2205 offers nearly twice the strength of 316L and superior resistance to chloride stress corrosion cracking, making it ideal for structural supports and utility lines.
Yes, we maintain a controlled inventory of key semiconductor alloys and partner with premium mills to offer stable supply and fast delivery for critical project timelines.
