Erasteel Silver steel round bar, 5mm

Erasteel silver steel round bar in 45 metric diameters from 5mm to 50mm, each in a 1m length. Its STUBS silver steel is to BS1407 analysis with 0.35% to 0.45% chromium added, for uniformity of machining and consistency of microstructure in hardening and tempering.

It is hardened by quenching in clean water or, preferably, 10% brine, then tempered to the hardness you need.

Where this product is used

• Tools such as punches, scribers and pins that are machined and then hardened and tempered
• Gauge blanks and precision tooling parts
• Shafts and pins that are machined to size and then hardened
• Work that needs uniform machining and a consistent response to heat treatment

Features

• Closely controlled analysis: carbon 0.95% to 1.20%, chromium 0.35% to 0.45%, manganese 0.25% to 0.45%, silicon 0.10% to 0.25%
• Controlled annealing to the maximum degree of spheroidisation, for easier and more uniform machining
• Surface finish that can be used without further grinding or polishing
• Hardens in clean water or preferably 10% brine, to a maximum of 66 Rockwell C

Key specifications

Choosing the right option

Choose the diameter closest to your finished size, so there is less to remove when machining. The table shows every size with its model code and the diameter tolerance that applies to it. For fractional-inch diameters see the imperial silver steel round.
