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:
