It Covers Low Carbon Nickel Chromium Molybdenum And Copper Alloy With Most Versatile And And Corrossion Resistant Alloy. It Gives Good Resistance To Corrosion To Oxidizing And Cracking While Superior Resistance To Localized Corrosion. They Are Widely Used In Chemical Processing Industries.
Hastelloy C 2000 Bolts — Specifications & Dimensions
Hastelloy C 2000 bolts are externally threaded fasteners with an integral head, manufactured per ASME B18.2.1, ISO 4014/4017, and DIN 933/931. TorqBolt produces Hastelloy C 2000 bolts in metric (M6–M100) and imperial (1/4"–4") diameters with custom lengths from 10 mm up to 3000 mm.
Head Styles Available
Hex head — ASME B18.2.1, the workhorse for general bolting
Heavy hex head — thicker head for high-load joints, ASTM A325 / A490 patterns
Socket head cap (SHCS) — ASME B18.3 / DIN 912, ideal where space is limited
Hastelloy C 2000 bolts are supplied with full or partial threading. Full-thread (UNC, UNF, ISO metric coarse/fine) for tension-only joints; partial-thread shank for shear loads where the unthreaded grip carries the load. Thread fits per ASME B1.1 (Class 2A) or ISO 965 (6g) by default; tighter Class 3A / 4h6h fits available on request. Engagement length follows the 1.5×D rule for tapped holes; 1.0×D minimum on through-bolting.
Mechanical Performance
Hastelloy C 2000 bolts achieve characteristic tensile strength, yield, and elongation per the source-material spec, with proof-load testing and hardness verification per ASTM F606 / ISO 898-1. Torque-tension calibration is published per ASME PCC-1 for critical joints. Each lot ships with EN 10204 3.1 (or 3.2 on request) certificates listing chemistry, mechanicals, hardness, and dimensional inspection.
Custom Configurations
TorqBolt can produce Hastelloy C 2000 bolts to drawing, with non-standard heads, drilled-shank variants, double-end, captive, or matched-set configurations. Coatings include zinc, PTFE, Xylan, hot-dip galvanized, and electroless nickel. NACE MR0175 / ISO 15156 sour-service certification on request.
Hastelloy — Ni-Cr-Mo / Ni-Mo Corrosion Alloys
Hastelloy is the trade designation for a family of nickel-chromium-molybdenum (and nickel-molybdenum) alloys formulated for severe wet-corrosion service: hydrochloric acid, sulfuric acid, chloride pitting, crevice corrosion, and sour wells.
Hastelloy C-276 (UNS N10276) is the workhorse: ~16% Cr, 16% Mo, 4% W gives unmatched resistance to oxidizing + reducing chloride media, the only nickel alloy resistant to wet chlorine + hypochlorite. Hastelloy C-22 (N06022) is upgraded with higher Cr for better oxidizing-acid performance. Hastelloy C-2000 (N06200) adds Cu for superior performance across the full pH range. Hastelloy B-3 (N10675) is Ni-Mo for hot HCl service. Hastelloy G-35 (N06035) targets phosphoric-acid plants.
Hastelloy fasteners ship per ASTM B574 / B575 (rod/bar/plate), with EN 10204 3.1 / 3.2 certification including PMI and intergranular-corrosion testing per ASTM G28. The ASTM A193 grade B14 + B7M designations cover Hastelloy bolting for ASME pressure-vessel use. NACE MR0175 / ISO 15156 sour-service compliance is standard. Welding requires matching filler metal (Ernicrmo-4 for C-276) with no post-weld solution anneal.
