The present study is concerned with the effect of filler metals such as austenitic stainless steel, ferritic stainless steel and duplex stainless steel on tensile and impact properties of the ferritic stainless steel conforming to AISI 409M grade. Rolled plates of 4 mm thickness were used as the base material for preparing single pass butt
welded joints. Tensile and impact properties, microhardness, microstructure and fracture surface morphology of the joints fabricated by austenitic stainless steel, ferritic stainless steel and duplex stainless steel filler metals were evaluated and the results were reported. From this investigation, it is found that the joints fabricated by
duplex stainless steel filler metal showed higher tensile strength and hardness compared to the joints fabricated by austenitic and ferritic stainless steel filler metals. Joints fabricated by austenitic stainless steel filler metal exhibited higher ductility and impact toughness compared with the joints fabricated by ferritic stainless steel and duplex stainless steel filler metals.

本文通过金相和EBSD等技术，观察了不同热轧终轧温度对00Cr21Mo1铁素体不锈钢热轧态、热轧退火态、冷轧退火态织构的变化的影响情况，并分析讨论了较高终轧温度下铁素体不锈钢00Cr21Mo1塑性应变比（Rm）较低的原因。结果表明，较低的终轧温度下，00Cr21Mo1热轧态组织形变带宽度较小，受轧辊切应变而形成的{110}<001>、{110}<112>、{4 4 11}<11 11 8>织构组分强度较小，且均匀、分散，最终冷轧退火态以{111}面织构为主，塑性应变比较高。
