Лист из Хастеллой C2000
Hastelloy C2000 plate is a high-performance,flat-rolled superalloy component manufactured primarily from a nickel-chromium-molybdenum system with a deliberate addition of copper.
Unlike older nickel alloys that excel only in either oxidizing or reducing environments,the unique chemistry of a C2000 plate allows it to thrive in both conditions simultaneously.

Hastelloy C2000 VS Other C-series
The single most critical element is copper,combined with a high chromium and molybdenum chemistry.While older alloys like Hastelloy C-276 excel in either reducing or oxidizing environments,this specific chemistry creates a metallurgical breakthrough:
Delivers exceptional resistance to heavily reducing,non-oxidizing acids,specifically expanding temperature and concentration limits in sulfuric acid.
Maximizes protection against strongly oxidizing media,ferric/cupric ions,and dissolved oxygen.
Prevents localized pitting and crevice corrosion in severe halide and chloride-rich environments.
Safeguards the plate against grain-boundary carbide precipitation during welding,maintaining full heat-affected zone corrosion resistance without post-weld heat treatment.

Main Manufacturing Methods for Hastelloy C2000 Plate
Mill Production
Raw chemistry is transformed into certified plates via vacuum induction melting and electro-slag remelting to eliminate impurities.Ingots are hot rolled into flat profiles between 1235°C and 950°C.Finally,plates undergo solution annealing at 1150°C to dissolve secondary phases,followed by a rapid water quench to lock the corrosion-resistant microstructure.
Structural Cutting & Machining
Due to extreme tensile strength,plates require high-definition plasma or laser cutting,while oxy-fuel cutting is banned to prevent carbon contamination.C2000 work-hardens instantly,demanding rigid heavy equipment,ultra-sharp carbide tools,positive rake angles,and deep,continuous feed depths to efficiently cut past the hardened surface layers.
Forming & Shaping
Plates are cold rolled or hot pressed into vessel shells and dished heads.The material has high ductility but requires heavy machinery to overcome immense spring-back forces.If cold forming deforms thickness past 15%,intermediate solution annealing is mandatory.Hot forming operates within 1040°C to 1180°C.
Welding & Joint Fabrication
Welding requires precise thermal management using TIG or MIG processes,while submerged arc welding is prohibited.Interpass temperatures must stay under 93°C to prevent micro-segregation.Due to ultra-low carbon,post-weld heat treatment is unnecessary,and standard thermal stress relief is avoided to prevent alloy embrittlement.
FAQs About Hastelloy C2000 Plate
- The Problem:
SAW generates incredibly high heat input and slow cooling rates. - The Damage:
This thermal lag forces secondary intermetallic phases to precipitate out of the nickel base.This drastically decreases the alloy’s structural ductility and corrosion resistance. Use TIG (GTAW) or MIG (GMAW) instead.
Нет.Thanks to its ultra-low carbon threshold,grain-boundary carbide precipitation is prevented during standard welding.
Standard thermal stress-relief cycles (~650°C) cause severe alloy embrittlement.If code rules mandate stress-relief,a full solution anneal at 1149°C followed by a water quench must be performed.

Standard austenitic stainless steels easily crack or pit in chlorine or halide environments.
C2000 has a massive Molybdenum content,giving it an exceptionally high PREN.It remains virtually immune to localized pitting and chloride-induced SCC.
