Torque specifications, especially for critical joints, should be determined under actual assembly conditions due to the many variables involved which are difficult … The mechanical properties of stainless steel (eg strength, ductility), and how well the alloy Engineering Book Store bolting torque table 3 - use only with a193 b8, cl1 bolts at 540°c - 650°c on uninsulated flanges. You can go ahead with tightening the stud in the pre-define torque sequence mentioned here. For a lubricated bolt, torque values ranged from 7.3Nm to 8.5Nm for 4.4kN to 5.5kN tension range. To answer this question, you first need to know some basic information about stainless steel. 3. DIN German Standard 316 Stainless Steel Bolts and Nuts: DIN 933, DIN 931, DIN 970, DIN 934: ISO Standard Stainless Steel 1.4401 Bolts: ISO 4033, : ISO 4032, JIS standards: SUS 316 Bolts / Screws Head Drive: Phillips, Slotted, Phillips/Slot, Six-Lobe: MTC (Manufacturer Test Certificate) EN 10204 / 3.1: Stainless Steel S31600 Nut Bolt Finishing bolting torque table 5 - ptfe coated astm a193 b7 and astm 193 b16 stud bolts. It is a function of the materials' frictional characteristics, which are based on surface finish, coatings and so on. The smaller ones such as the M4 sizes have about 2.7Nm torque while the larger ones have larger torque values. For a non-lubricated bolt, torques of 13Nm - 14Nm were required to develop tensions of 3.5kN to 6.2kN. For standard bolt torques use 0. I’ve noticed a high tendency for both 304 and 316 grade stainless bolt and nut combinations to gall upon installation and removal after being exposed to the environment for a period of time even if installed properly. �F]��Tzh�~���h��d�Ů��y+����c��|�?�w�j���.#$?��)!
