Frequently Asked Questions
What is the difference between 304 and 316 stainless steel?
316 stainless steel contains molybdenum which provides better corrosion resistance, especially in chloride environments, compared to 304. 316 is more suitable for marine and chemical processing applications.
Can you provide bars with special surface finishes?
Yes, we offer various surface finishes including cold drawn, hot rolled, polished (up to mirror finish), and pickled. Special finishes can be arranged upon request.
What is the maximum diameter you can supply?
Our standard range goes up to 300mm diameter. For larger diameters, please contact our sales team to discuss special requirements.
Do you provide material test reports with the shipment?
Yes, we provide full material test reports (MTRs) with every shipment, including chemical composition, mechanical properties, and other relevant test data.
