Frequently Asked Questions About SMO 254 Sheets & Plates

What is SMO 254 material grade?

SMO 254 is a high-alloy austenitic stainless steel containing 6% molybdenum and nitrogen. It was specifically developed for excellent resistance to crevice and pitting corrosion, making it ideal for demanding applications in the pulp and paper industry, as well as for offshore oil and gas platforms.

What is the difference between SMO 254 and SS316?

SMO 254 offers significantly higher corrosion resistance, strength, and heat resistance than standard stainless steel 316. While it provides superior performance in aggressive environments, it is more difficult to machine and requires specific filler materials for welding.

Is 254 SMO magnetic?

254 SMO has very low magnetic permeability, meaning it is non-magnetic. Its high impact strength and ability to withstand sub-zero temperatures make it a durable and reliable material for various environments.
