What types of round bars does Ragnar Metals & Tubes manufacture?

Ragnar Metals & Tubes manufactures stainless steel round bars (Grade 304, 316L, 321, 347, 17-4PH), duplex steel (2101, 2205, 2304, 2003), super duplex (2507, Zeron 100), hyper duplex (UNS S32707, S32808, S33207), nickel alloys (Inconel 625, 718, Hastelloy C-276, Monel 400, Titanium Grade 2 & 5), and copper alloys (copper, brass, aluminium bronze, phosphorus bronze, beryllium copper, gunmetal, aluminium).

What diameter range is available for round bars?

Round bars are available from Ø 6 mm to Ø 500 mm in hot-rolled, cold-drawn, bright bar, peeled and polished finishes per ASTM A276, A479, A564, ASME SA276, SA479, EN 10272, EN 10088-3, DIN and JIS standards.

Do you supply mill test certificates with round bars?

Yes. All round bars are supplied with EN 10204 3.1 or 3.2 mill test certificates from approved mills. PMI testing, NACE MR0175/MR0103 compliance and third-party inspection are available on request.

Which countries do you export round bars to?

We export round bars to 40+ countries including UAE, Saudi Arabia, Qatar, Oman, Kuwait, Bahrain, USA, UK, Germany, Canada, Australia, Singapore, Malaysia, Indonesia, South Africa and Korea.

Can you supply custom-cut or machined round bars?

Yes. We supply round bars in custom lengths, cut-to-size, rough-turned and precision-machined dimensions as per project requirements. Contact us for minimum order quantity and lead time by grade.

What is the difference between duplex and super duplex round bars?

Duplex round bars (e.g. 2205, PREN 28–38) combine austenite and ferrite for twice the strength of standard stainless steel with good corrosion resistance. Super duplex (e.g. 2507, Zeron 100, PREN greater than 40) adds more Cr, Mo and N for superior resistance to pitting and crevice corrosion in seawater and chloride-rich media. Hyper duplex (PREN greater than 48) is specified for the most demanding subsea and chemical duty.

Are Ragnar Metals & Tubes round bars ISO 9001 certified?

Yes. Ragnar Metals & Tubes is ISO 9001:2015 certified. Round bars comply with ASTM A276, A479, A564, ASME SA276, SA479, EN 10272, EN 10088-3 and other applicable international standards.
