Product Description

iso gr10.9 qt steel round bar

Iso grade 10.9 is one of anchor bolt or threaded rod steel grades in standard iso 898. Iso gr10.9 qt steel bar raw mateirals include 5140 to Gr 10.9 or 4140 to Gr10.9. 40Cr or 5140 to iso grade 10.9 is usualy for smaller diamters below M60. 42CrMo or 4140 to iso grade 10.9 is usually produced for bigger diameter from 60mm to 100mm. iso grade 10.9 steel grade mechanical proeprties are higher than iso grade 8.8. We can produce iso gr 10.9 hot rolled and qt steel round bar and iso gr 10.9 cold drawn and qt steel round bar according different usage.10.9 steel bar we produce is fully threaded stud bolts used for high strength steel bolts such as marine anchor bolt, mine steel anchor bolt, wind turbine anchor bolt. iso 10.9 qt steel bar we produce is fully threaded stud bolts used for high strength steel bolts such as marine anchor bolt, mine steel anchor bolt, wind turbine anchor bolt.

The high stensile steel bars we produce, diameters from 8mm to 100mm with length 1m to 12m.

The advantage of high tensile steel bars for high tensile anchor bolts we supply:

Consistent mechanical properties

Even thickness on the whole bars

Deep mechanical properties

Even hardness on the whole bars/Tougher and Increased strength

No brittle, UT testing/Precision size tolerance/Good straightness

Good Roughness/Professional technical service/Competitive price/Fast delivery

The steel grade which can be used to produce high tensile steel bars for high tensile anchor bolts on offshore wind turbine.

Grade 10.9 high tensile steel bars mechanical properties:
