→Used in 180 degrees bending test and check whether there is crack after test in bending plastic deformation for plain round bar, ribbed bar, straight steel bar, steel tube, etc.
→Used for bending test of steel bar for HPB235,HPB300,HRB335/HRBF335、HRB400/HRBF400,HRB500/HRBF500,CRB550,CTB550/CTB650 (Diameter less then 40mm).
→51mm and 60.3mm steel pipes bending testing machine is used to determine the ability of full-section metallic tubes of circular cross-section to undergo plastic deformation in bending. It is intended for tubes with an outside diameter no greater than 51mm.
→Used in 10° bending test, 30° bending test, 90° bending test for steel-plastic composite pipe with diameter no greater than 40mm.
→ISO 7348 Metallic materials-Bend test
