Stainless steel CNC machining, duplex stainless, tool wear, and surface finish guides.
Machining S44400 (EN 1.4521) Ferritic Stainless Steel: Pitting Resistance Near 316 Without the Nickel
If your part sits in warm or mildly chlorinated water and 316 keeps cracking under stress-corrosi
worldstainless released the 2026 Stainless Steel in Figures statistical yearbook on June 23. What the grade production, trade flow, and consumption data means for CNC machining buyers sourcing 304, 316L, and duplex stainless parts.
World crude steel production fell 1.5% YoY through May 2026 to 773.1 Mt. North America grew 5.9%, China contracted 3.9%, and India rose 7.8%. Regional divergence in steel supply signals different pricing, lead time, and certification requirements for CNC buyers.
