Perforation Behavior of 304 Stainless Steel Plates at Various Temperatures

Compressibility of 304 Stainless Steel Powder Metallurgy Materials Reinforced with 304 Short Stainless Steel Fibers

Powder metallurgy (P/M) technique is usually used for manufacturing porous metal materials. However, some P/M materials are limitedly used in engineering for their performance deficiency. A novel 304 stainless steel P/M material was produced by a solid-state sintering of 304 stainless steel powders and 304 short stainless steel fibers, which were alternately laid in layers according to mass rat...

Evolution of Microstructure and Residual Stress under Various Vibration Modes in 304 Stainless Steel Welds

Simultaneous vibration welding of 304 stainless steel was carried out with an eccentric circulating vibrator and a magnetic telescopic vibrator at subresonant (362 Hz and 59.3 Hz) and resonant (376 Hz and 60.9 Hz) frequencies. The experimental results indicate that the temperature gradient can be increased, accelerating nucleation and causing grain refinement during this process. During simulta...

Magnetic Properties of Metastable 304 Stainless Steel with Bcc Structure

Ordinary 304 stainless steel has a fcc structure and is non-magnetic at room temperature. By using a vapor quenching method, we have fabricated single-phase metastable bcc 304 stainless steel which is strongly ferromagnetic with a magnetization of 130 emu/g and a Curie temperature in excess of 550 OC. Upon subsequent annealing above 550 OC, the metastable bcc state transforms back into the usua...

Corrosion Performance and Tribological Properties of Carbonitrided 304 Stainless Steel

Microstructural analysis of expanded stainless steel 304 cylinders

A gas-gun technique to radially expand cylinders of a chosen material, based on a technique developed in 1979, has recently been re-established. Stainless steel 304 cylinders of length 160 mm, internal diameter 67 mm and thickness either 0.5 or 1.5 mm have been expanded using a 70 mm bore single-stage gas-gun. Microstructural analysis of the recovered specimens was performed using optical micro...
