Roughness (mm) Drawn Tubing, Glass, Plastic. 304 stainless steel yield strength at 0. Factor 1 sensors are readily available in stainless steel versions rated up to IP69K for high pressure and temperature washdown, so it is likely a version will be available to fit most applications. Type 304L Stainless Steel. Assuming you used an inside bend radius smaller than the material thickness, the K-factor (or neutral factor, if you prefer) in our cheesy example would be 0. 20 when bolts, nuts, and washers of the fastener joint. The constant volume law governs the bending process, the bend material particles distribution, and deformation types are also crucial for this process. Achieving Proper Bolt Torque: An Introduction to K-Factor. Absolute Roughness for Common Materials. The density of stainless steel 304 is 7,930 kg/m3 or 7. We are a specialist manufacturer of long radius elbows or pipe elbows in size range of 1/2″ to 48″ in accordance with ASME B16. When selecting a stainless steel for any corrosive environment, it is always best to consult with a corrosion engineer and, if possible, conduct tests in the environment involved under actual operating conditions. 5 ROUGHNESS MEASUREMENTS OF STAINLESS STEEL SURFACES Summary Although Ra values are commonly used to describe surfaces, the limits of this indicator should not be forgotten. The presence of chromium creates an invisible surface film that resists oxidation and makes the material “passive” or corrosion resistant. You can use this K-Factor calculator to calculate k factor using reverse engineering approach. Stainless Steel 304 and Stainless Steel 316. Not resistant to intergranular corrosion. 55 8. A few suffixes used with 304 with the major alterations in chemical composition are shown in below table-. 304 on 304 will gall at low stress (maybe a couple of ksi according to Armco). The material thickness (T), bending angle (A), inner bending radius (R), and K-factor of the. 5 µm”. The K-factor in sheet metal bending represents the ratio between the thickness of the metal and an invisible line called the “neutral axis. Yes. The hot working activation energy for steel 321 is significantly higher than that for 304 at 465 kJ/mol and 446 kJ/mol respectively which affects their respective Z parameters at otherwise equivalent conditions. Grade 440C is capable of attaining, after heat treatment, the highest strength, hardness and wear resistance of all the. Conductive heat transfer per unit area can be calculated as. For more data sheet, you can check 304 stainless steel properties. 304 stainless steel (304ss) is the most employed material in the water supply system (WSS), due to its attractive combinations of mechanical properties and corrosion resistance [1, 2]. 304 stainless steel is one of the most popular types of stainless steel.
