1 Scope This document specifies the mechanical and physical properties of bolts, screws, studs and nuts, with coarse pitch thread and fine pitch thread, made of corrosion-resistant stainless steels (i.e. martensitic stainless steels and precipitation hardening austenitic stainless steels ) and nickel alloys, intended for use at high temperatures up to 800 °C. Tests in accordance with Clause 9 are performed at the ambient temperature range of 10 °C to 35 °C, and other tests can be performed at higher temperatures, see Clause 10. NOTE Fasteners specified in this document are also suitable when used at low temperatures, typically down to -50 °C. For more information, see ISO 3506‑6. The term “fasteners” is used in this document when bolts, screws, studs and nuts are considered all together. ISO 3506‑6 provides general rules and additional technical information on suitable stainless steels and nickel alloys as well as their properties. This document applies to fasteners: — with ISO metric thread in accordance with ISO 68‑1, — with diameter/pitch combinations in accordance with ISO 261 and ISO 262, — with coarse pitch thread M3 to M39, and fine pitch thread M8×...
BS ISO 3506-5:2022 是基于 ISO 3506-5 的发版本。
锌合金最大的特点就是与锌镀层相比,具有较高的耐蚀性,并具有良好的防护性和性价比值随着工业技术的发展,对防腐技术的要求越来越高。尤其在恶劣环境中,以往常规的防腐手段,如发蓝、镀锌、浸锌等已不能满足紧固件等钢铁构件的长效防腐要求。 而电镀锌镍合金技术具有高耐蚀、薄镀层、低氢脆、可加工、易操作等特点。可广泛应用于汽车工业、紧固件工业、电缆桥架、高速公路护栏及海水环境中的钢构件等的防腐处理。 ...
应用概况与特殊要求 该合金主要用于制造航空发动机工作温度-200~+600 ℃以下的耐腐蚀的平面波形弹簧、周向螺旋弹簧、螺旋压簧、弹簧卡圈和密封圈等零件●30W4Cr2VA 牌号:30W4Cr2VA 冷拉弹簧丝 标准:GB/T 1222-1984 特性及适用范围: 由于钨铬钒的作用,此钢有良好的室暖和高温力学性能和非凡高的淬透性,回火稳定性佳,热加工性能良好。...
方头螺栓的方头有较大的尺寸和受力表面,便于扳手口卡住或靠住其他零件起止转作用,常用在比较粗糙的结构上,有时也用于T型槽中,便于螺栓在槽中松动调整位置。见GB8、GB5780~5790等。 b) 铰制孔用螺栓:使用时将螺栓紧密镶入铰制孔内,以防止工件错位,见GB27等。 c) 止转螺栓: 有方颈、带榫之分,见GB12~15等; d) 特殊用途螺栓:包括T型槽用螺栓、活节螺栓和地脚螺栓。...
