不锈钢的用途,以日本为例,一向主要用于制作餐具和厨房器具,发展已趋稳定。近年,不锈钢的用途则转向建材、汽车和机电领域,形成新的三大用途,并且还在不断发展。 建材用不锈钢 1.结材用不锈钢 在建筑上作结构材料使用是近年才发展起来的。1989年日本制定了《不锈钢结构设计施工准则》条例,规定的结构材料为PS235—SUS304钢。此外,还规定了建筑物的规模:栋高15m以下、檐高10m以下、开间宽度20m以下,面积3000m~2以下。在这个范围内可完全使用PS235—SUS304钢。日本已建了六座以不锈钢为结构材料的小楼房作为示范建筑物。日本还打算扩大建筑物的规模,提高钢的强度和耐蚀性,增加新钢种,如SUS304N、316、329J4L钢。
The use of stainless steel, for example in Japan, has always been mainly used for the production of tableware and kitchen utensils, the development has stabilized. In recent years, the uses of stainless steel have turned to building materials, automobiles and electromechanics, forming three new uses and are still evolving. Stainless steel building materials 1. Knot material Stainless steel construction materials used in the building in recent years developed. Japan in 1989 formulated the “stainless steel design and construction guidelines,” Ordinance, the provisions of the structural material PS235-SUS304 steel. In addition, the size of the building is also stipulated: building height 15m below, eaves high 10m below, open space width 20m below, area 3000m ~ 2 below. In this range can be fully used PS235-SUS304 steel. Japan has built six small buildings made of stainless steel as a model building. Japan also intends to expand the scale of the building, increase the strength and corrosion resistance of steel, and add new types of steel, such as SUS304N, 316,329J4L steel.
