500B steel tensile strength ans yield strength, elangation vedeo kardo... Its very important for me... Because iam using above steel and i want to compare with you. I am senior technicain in Gulf testing solutions (GTS LAB) in oman...
In the re-bend test, the bar is bent at an angle of 135 degrees. Keep the TMT bar in boiling water at 100 degrees for 30 minutes, followed by cooling down the same. Once cooled, twist it again to 157.5 degrees and check for rupture or cracks. The TMT bar shall be deemed to have passed the test if there is no rupture or crack visible at the bend portion (tension zone) to a person with normal vision
1. Bend aur Rebend test karne ka ya bilkul sahi tareeka hain jiske baare zyada tar log jaagruk nahin hain. 2. Generally log jis sariya ko 180 deg pe bend karte hain, phir ussi sariya ko seedha karte hain aur isko rebend test ka naam dete hain. Aisa koi test BIS mein nirdharit nahin hain kyunki practically socha jaaye to concrete ke andar pada sariya itna zyada bend ho hi nahin sakta. 3. JSW aur JSPL jaise brand logo ko galat bend rebend test dikha ke ullu banate hain. 4. Achi quality ke sariya mein Sulphur aur Phosphorus jaisi ashudhiyo ki maatra IS 1786 ke according honi chahiye. Aur sabse zaroori hain ki sariya ki strength, elongation aur UTS/YS ratio achi honi chahiye. IS 13920 14.5% min elongation aur min 1.15 UTS/YS ratio recommend karta hain.
1 Tangent Modulus of Elasticity: EB 5 L3 m/4bd 3 (6) where: EB = modulus of elasticity in bending, MPa (psi), L = support span, mm (in.), b = width of beam tested, mm (in.), d = depth of beam tested, mm (in.), and m = slope of the tangent to the initial straight-line portion of the load-deflection curve, N/mm (lbf/in.) of deflection.
