哈氏合金紧固件, 锆705紧固件, 英科乃尔紧固件,蒙乃尔紧固件和特殊不锈钢紧固件(详见http://www.shndco.com)
我公司是进口哈氏合金(Hastelloy), 蒙乃尔400/500(Monel400/500), 英科乃尔(Inconel) 和锆702/705)材料专业经销商及上述特殊材料制造紧固件专业制造商. 特殊材料紧固件被广泛用于醋酸装置,醋酐装置,石油,化工,制药,电厂,船舶和其他领域
由于哈氏合金,英科乃尔和蒙乃尔材料具有高强度、高韧性和极强应变冷作硬化倾向力学特点,所以制造这些特殊材料紧固件存在大的难度.为确保制造优质特殊材料紧固件,我公司掌握成熟制造技术并有严格控制整个制造工艺系统. 首先, 为避免六角螺栓的六角头锻打中产生微裂纹, 六角头锻打须严格控制在一定温度范围内锻打成型. 哈氏B3锻打温度须控制在1232 C°(开始锻打)和在982 C°(结束锻打),哈氏C276锻打温度须控制在1232 C°(开始锻打)和在954 C°(结束锻打). 其次,按照紧固件制造规范/标准,为保证螺栓和螺母在标准范围内的锁紧力,选择合适刀具才能满足加工螺纹制造精度,因为这些特殊材料具有高强度、高韧性和极强应变冷作硬化特性
紧固件:六角螺栓/螺母,内六角螺栓/螺母,双头螺栓/螺母,U型螺栓/螺母,螺钉/螺母,卡子螺栓/螺母(用于塔板联接),平垫片和弹簧垫圈等
标准:GB5782 GB5783 GB70 GB 6170 DIN931/933/603/444, ISO4014/4017/8677, ASME B18.2.1/B18.2.2 /B18.2.3.1M/B18.2.4.1M 和特制螺栓等
材料:哈氏C276,哈氏B3,哈氏C22,锆705,蒙乃尔400,英科乃尔600/800/625/825,904L, AL6XN, 2205等
从1997年起,我公司已为许多***国外独资,合资,大型国内企业提供哈氏C276, 哈氏B3,锆705,蒙乃尔400,英科乃尔材料紧固件,有些公司定制上万套哈氏合金紧固件,例如拜耳材料科技(中国)有限公司,重庆扬子乙酰化工有限公司(BP)(醋酸厂), 山东华鲁恒升化工股份有限公司(醋酸和醋肝), 北京泽华化学工程有限公司,烟台巨力异氰酸脂有限公司和苏州诺华制药科技有限公司等

Our corporation is a importer of submitting special materials of Hastelloy ,Inconel,Monel and Zirconium 702 / 705 as well as a manufacturer of fabricated fasteners of above material. The fasteners are widely used in the fields of acetic acid , acetic anhydride ,petrochemical, chemical , pharmacy, power, marine and other industries.
As it has high intensity and tenacity as well as stong strain hardening tendency for the mechanical properties of Hastelloy ,Inconel and Monel alloy, it has certain difficulty to fabricate the fastener. To ensure excellent quality for the fasteners, our company employs upclass fabricating technology and has formed a control system during whole manufacturing process. Firstly, In order to avoid forming micro cracks in the bolt during forging hex head process, it must be heated In certain temperature range to forge the hex head. During the forging process, the 1232 C°is start forging temperature and 982 C°is finished forging temperature for Hastelloy B3. While for Hastelloy C276, 1232 C°is start forging temperature and 954 C°is finished forging temperature. As for fabricating standard/code for fastener, it must have good locked force both the boltand nut. So it is very important to select correct cuttting tool , because there are the properties of high intensity and tenacity as well as cold hardening for the special material.
Product: Hex bolts/ nuts, Inside hexagonal bolt/ nuts, Threaded studs/nut, U-bolts/nut; Bands bolt /nut, flat washers, spring washers etc
Material: Hastelloy C-276,Hastelloy B3,HastelloyC22,Zirconium705,Monel 400,Incoloy600/ 800/ 825,904L, AL6XN , 2205 etc.
Standard/Code: GB5782 GB5783 GB70 GB 6170 DIN931/933/603/444, ISO4014/4017/8677, ASME B18.2.1/B18.2.2 , ASME B18.2.3.1M/B18.2.4.1M, special bolts
Since 1997, we have submitted a lot of the fasteners for Haste loy C276, Hastelloy B3, Zirconium 705,Monel 400 and lnconel alloy for many famous corporations both domestic and overseas. Some clients have purchased tens of thousands of sets of Hastelloy bolt in an order. such as Bayer Material Science (China) Co., Ltd.,Chongqin Yangtze (BP) River Acetyls Co.,Ltd (Acetic acid plant), Shandong HuaLu Hengsheng Chemical Co., Ltd.,.(Acetic acid plant), Beijing ZeHua Chemical Engineering Co., Ltd., YanTai JuLi Cyanate Fat Co., Ltd.,.and SuZhou Novartis Pharmaceutical technology Co., Ltd. and many corporations.
