Product Description

Grade 8.8 B7 105 qt steel bar


ISO Grade 8.8, 10.9, 12.9 steel round bar are ISO 898 standard qt steel bar which is used to produce Threaded Steel Rod, bolts, nuts, screws etc.

Grade B7 and B16 steel round bar are ASTM A193 standard qt steel bar which is used to produce threaded steel rod, bolts, nuts, screws etc.

Grade 36, Grade 55 and Grade 105 are ASTM F1554 standard steel grades for steel bolts, nuts and screws etc. 


Above grades are all heat treated steel bar especially Quenched And Tempered Steel Bar to get higher hardness, strenth and uniform microstructure which benefits the usage of steel bar.


ISO Grade 8.8, Grade 10.9, Grade 12.9, ASTM A193 Grade B7, B16 and ASTM F1554 Grade 36, Grade 55 and Grade 105 quenched and tempered q&t steel bar we supply includes following advangtages:

^ Consistent mechanical properties

^ Deep mechanical properties (from surface to the center according to your requirement)

^ 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

Company Overview

Shandong Le Ren Special Steel CO., Ltd. owns three factories to produce all kinds of steel rod, steel bar and finished steel products. Among three factories, one is to produce steel bars such as annealed, normalized and quenched and tempered steel bar and pipe, cold drawn, peeled, ground and polished steel bar etc; one is to produce threaded or knurled steel rod and steel bar; another one is to do steel bar, steel rods or steel pipe machining. 


In the tactories, we have complete and advanced production, inspection and testing facilities such as shot blasting machines, cold drawing machines,straightening machines, annealing furnace, quenching and tempering furnaces, threading machines, cnc machines, welding machines etc, and inspections and testing facilities to inspect dimension tolernaces, corner radius, length, straightness, surface roughness, mechanical properties, AKV, UT testing, Eddy testing and MPI testing etc. All of these, including more than twenty years production and exporting experiences, we can supply you good quality products and services.

Production Certification
Inspection

Our factory is equipped with complete inspection and testing facilities to inspect steel bar dimension tolernaces, corner radius, length, straightness, surface roughness, mechanical properties, AKV, UT testing, Eddy testing and MPI testing etc.


Packing & Delivery

Most of our steel bar are cold drawn, peeled, ground and polished steel bar which require good surface and straightness. So steel bar packing is very important to keep good quality. We use several kinds of steel bar packing according to your technical requirements.
