40Cr 40Cr Hot rolled and qt steel bar
40Cr steel material is one of most common used materials to produce iso grade 8.8 material. 40Cr qt steel bar can be produced as iso grade 8.8 chemical composition to be used to produce iso grade 8.8 Threaded Rods and iso gr 8.8 anchor bolt, 40Cr to iso gr8.8 hot rolled and qt steel bar is used to produce anchot bolt. ISO grade 8.8 is one kind of alloy quenched and tempered grade in ISO898 standard which is similar to US grades 8 and B7. Except 40Cr to gr8.8 hot rolled and qt steel round bars, we can also produce 40Cr to iso gr 8.8 Cold Drawn Steel Bar with straightness and precision diameter to produce the threaded rods.
