the pipe bending should be made with a pipe with a positive wall thickness tolerance. the bending radius of the high-pressure steel pipe should be greater than 5 times the outer diameter, and the bending radius of other pipes should be greater than 35 times the outer diameter of the pipe; when makin

which is better between 304 and 316 stainless steel? what is the difference between 304 and 316 stainless steel? which 304 or 316 stainless steel is more suitable for food grade use? in fact, both 316 and 304 stainless steels are austenitic stainless steels, which have good rust resistance and corro

1、the physical properties of stainless steellike other materials, the physical properties mainly include the following three aspects: thermodynamic properties such as melting point, specific heat capacity, thermal conductivity and linear expansion coefficient, electromagnetic properties such as elec

alloy 317l (uns s31726, 00cr19ni13mo3) is an austenitic stainless steel based on molybdenum. compared with conventional chromium-nickel austenitic stainless steels such as 304 alloy, it has stronger resistance to chemical corrosion. in addition, compared with conventional stainless steel, 317l alloy

s32760 is a high-alloy super duplex stainless steel, mainly used in various strong corrosive environments. s32760 dual-phase steel has strong strength and corrosion resistance, and is mainly used in chemical processing, petrochemical and subsea equipment. it has strong resistance to chloride corrosi

253ma/unss30815 is a kind of heat resistant stainless steel developed on the basis of 21cr-11ni stainless steel by alloying rare earth elements ce and cn. generally, 253ma is austenite. due to the interaction of rare earth elements and silicon, the material still has good oxidation resistance at 115

the welding characteristics of austenitic stainless steel: the elastic and plastic stress and strain during the welding process are very large, but cold cracks are rarely seen. there is no quenching hardening zone and grain coarsening in the welded joint, so the tensile strength of the weld is relat

sometimes the cable ladder is installed through the wall. if one side of the wall catches fire, heat may be transferred from the fired side to the other side of the wall, causing danger. therefore, a test was conducted on a device that simulates a hollow wall. the cable ladder passes through the ins

observing the actually installed ladder frame, it is found that although the cable ladder frame is protected by fire, the supporting legs are not insulated and can conduct heat. the test was carried out on aluminum and stainless steel ladder frames covered with 100 mm ceramic fiber insulation. the l
