Hastelloy fasteners, Zirconium705 fasteners, Inconel fasteners,Monel fastener etc.
Our corporation is a importer of submitting special materials of Hastelloy ,Inconel,Monel and Zirconium 702 / 705 as well as a manufacturer of fabricating 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 the attributes of these special material include high resistance to uniform attact, outstanding localized corrsion resistance, excellent stress corrosion cracking resistance, excellent sea water resistance, wear- high temperature . These special material have become widely used by the oil and gas, chemical processing industries, phamaceutical, gas desulfurization industries, power, marine, especially acetic acid and acetic anhydride plants and many 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 and need very strict requirement for processing technology . In 1995, our technical personnels was sent to Haynes International Co. Ltd. in USA, which is a manufacturer
to manufacturing material for Hastelloy alloies , to study theoretical knowledge and fabricating technology for Hastelloy alloies
and took back a lot technical documents.
In order to ensure to fabricate the high quality fasteners for special material and been uesd for a long time during the state of hot and cold under the tensile stress, it is particularly important to fabricate the fasteners for special material according to following three technical requirement during whole fabricating process.
1.Special material: It is must to imported special material from USA and Europe. As the special material be manufactured accordind to strict execution ASTE material specifications / codes, it is stable and reliable for physical and chemical properties, especially the properties of corrosion resistance
2. Thermal processing:
As it has the mechanical properties of high intensity and tenacity for Hastelloy ,Inconel and Monel alloies , especially the characteristics of stong cold hardening tendency for Hastelloy. It has certain difficulty to fabricate the fastener. During fabricating the fasteners of special material, it has strictly requirement for controling each hot-working and heat treatment temperature process. So it will be avoided micro cracks occurring in the fasteners during cold drawn to asking for outer diametre size of round bars and hot-forging to form hex head of the bolts. Once the micro cracks in the fasteners bave been occurred, the micro cracks will be gradually grow in the fasteners under alternating tensile stress of colding or heating condition. The fasteners will be fractured in the short-time Thus, strictly control for whole manufacturing process of each heating operation is particularly important, Therefore, it has more strictly requirement to fabricate high quality fasteners for special material
a. During the forging process, the 1232 C°is start forging temperature and 982 C°is finished forging temperature for Hastelloy B3.
b. During the forging process, the 1232 C°is start forging temperature and 954 C°is finished forging temperature for Hastelloy C276.
3. Machining process:
Because Hastelloy materials has the mechanics characteristics of high strength and toughness as well as strong strain cold hardening tendency, it is very difficulty to machine the fasteners of Hastelloy. In order to ensure the manufacturing precision and good lock force of the fasteners according to fabricating and inspecting standards / codes for the fasterens, it is very important to choose the appropriate material to fabricate cutting tools. Otherwise, the fasterens will be inspected for bad products because the fastener thread depth is too shallow and rotten teeths, greatly reduce using life.
Our corporation makes the full used of its purchase channels at abroad and its rich experience in fabricting fasteners of special materials to submitted following fasterens of Hastelloy, Zirconium 705, Inconel and Monel.
