Duplex steel added to Sandvik hollow bar range

Duplex steel added to Sandvik hollow bar rangeKeywords: Sandvik Steel, Stainless steel

Further development of its Sanmac stainless steel hollow bar for machining has enabled Sandvik Steel to announce the addition to the range of duplex steel grade Sandvik Sanmac SAF 2205 (UNS S31803).

According to Sandvik it is suited particularly to applications where corrosion is likely, due to chlorides being present. They also state that Sanmac SAF 2205 duplex stainless steel has high resistance to stress corrosion bearing environments. It also reportedly has high resistance to general, pitting, crevice and erosion corrosion and to corrosion fatigue. Its mechanical strength is said to be roughly twice that of austenitic stainless steels and it offers good weldability.

Sanmac SAF 2205 hollow bar is also said to combine its excellent corrosion resistance with the enhanced machinability of the Sanmac steels. Key applications are seen as components for pumps and valves and mechanical seals for the petrochemical, oil and gas and food industries where erosion or chloride induced corrosion are a problem.

Manufactured in a size range from 32mm up to 250mm diameter and available from stock in a wide range of sizes, all Sanmac SAF 2205 hollow bar is stated to be corrosion and impact tested in accordance with standard oil and gas industry requirements.

A key feature of the supply of Sanmac hollow bar is Sandvik Steel's production and distribution capability. Production is located centrally at Sandvik's manufacturing plant in Sweden. This, it is believed, enables close control and monitoring of material properties from melt to melt and guarantees consistent machining quality from batch to batch.

Sanmac SAF 2205 can be supplied in the UK by TW Metals Ltd who are the exclusive distributors for standard 304/304L and 316/316L grades of Sanmac stainless steel hollow bar. TW Metals are located in Southampton, Tel: +44 (0)23 8073 9333; Fax: +44 (0)23 8073 9601; E-mail: sales@twmetals.co.uk.
