Nickel alloy round bar
Round bar from 6 mm upwards in 30 grades, supplied annealed or in the condition your drawing calls for, cut to length, peeled or ground.
Melted in our own furnaces in Shanghai, tested in our own laboratory, and released with a certificate that matches the marking on the material. EN 10204 3.1 or 3.2, with chemistry, mechanical results and heat-number traceability.

Three things that change the price
The same grade in the same form can differ by a wide margin on these three points alone.
The bar standard and the grade standard are not the same document.
ASTM B637 is the bar standard for 718; the grade is defined by its chemistry. When you quote one without the other, the mill has to guess the mechanical requirements.
Condition decides the properties, not the grade name alone.
Solution annealed and aged are two different products. For the age-hardenable grades the ageing treatment is part of what you are buying, and it belongs on the purchase order.
Cut length is a real cost lever.
Cutting to length at the mill removes a cut, a handling step and a remnant from your shop. Sending the finished length rather than the stock length usually pays for itself.
Round bar: questions buyers ask
Drawn from the same grade data as the table above.
What is the smallest round bar diameter you supply?
Round bar from 6 mm. Larger sizes are quoted against the standard and the condition on your order, including open-die forged bar for the biggest sections.
Do you peel, grind or cut to length?
Yes. Bar can be supplied peeled, ground or cut to length, and the surface condition is stated on the certificate so incoming inspection has something to check against.
Which standards does the bar come under?
Each grade is certified to the bar standard named on your order — for example ASTM B637 for 718, ASTM B166 for 600 and 625, ASTM A276 for the stainless grades. The full mapping is on the cross-reference table.
