Hexagon bars in UNS 32760 and ASTM A 453 Grade 660 A and D

Introduction

Producing nuts or small components with a Hexagon form has required the purchase of a specific Hexagon forging or alternatively machining from round bar. Machining from round bar is wasteful and very time consuming, resulting in a loss of 20 % of the material as a minimum!

In order to reduce costs and improve productivity for fastener and small valve body producers, Böhler UK have invested in Hexagon profile in two grades; UNS 32760 and ASTM A 453 grade 660 AD. The UNS 32760 is produced and tested to Norsok D 57 by our newly accredited Böhler Ybbstal Profile mill, which gained Norsok M650 approval in March 2012. All the material is certified and approved to API 6A PSL3, which includes the Heat treatment charts and the NDT testers’ qualification records. The ASTM A 453 Grade 660 is Heat treated to condition A and tested to D properties. Stress rupture tests have also been carried out and included in the test reports. We have also carried out Impact testing at Sub zero temperatures, as many oil and gas customers are now asking for this as a specific requirement. API 6A PSL 3 certification is standard. Both grades conform to NACE MR 0175.
