Castrol Iloquench heat-treatment quenching oils — Iloquench 1 (fast-quench for tough alloy steels), Iloquench 21 (delayed-quench for distortion-sensitive parts), Iloquench 25 (vacuum-furnace clean grade), Iloquench M (martempering for hot-quench at 150-200°C). Cooling-curve characterised, oxidation-life monitored. Vasundhara Specialities supplies the full Iloquench range across AP and Telangana with technical support for cooling-curve selection by alloy + part geometry + distortion target.
Complete Castrol coverage across the castrol iloquench quenching oils family.
Fast-quench heat-treatment oil for tough alloy steels and case-hardening service requiring maximum cooling rate. Standard cooling-curve characterised per Wolfson / IFHTSE benchmark. For alloy-steel hardening, gear-blank case-hardening + tough-steel through-hardening service.
Delayed-quench heat-treatment oil for distortion-sensitive parts. Slower cooling rate vs Iloquench 1 — reduces thermal gradient and resulting distortion. For thin-section parts, complex geometries + low-distortion-budget heat-treatment programmes.
Vacuum-furnace heat-treatment oil. Low vapour pressure (minimises vacuum-pump loading), low oxidation product formation. For clean-furnace operations + aerospace / medical-grade components requiring minimal surface contamination.
Martempering quench oil for hot-quench operations at 150-200°C bath temperature. Reduces distortion via interrupted-cooling between austenitising and tempering. For complex-geometry tooling + aerospace components.
Castrol's specialty grades for specific application-OEM heat-treatment programmes — austempering oils, isothermal-quench oils, water-emulsion quenchants where specified. Cross-reference your specific OEM heat-treatment specification with our technical team.
Standard property values across the range. TDS / MSDS / per-batch COA available on enquiry.

Common questions from maintenance + procurement buyers sourcing Castrol Iloquench Quenching Oils through Vasundhara Specialities.
Select Iloquench 1 fast-quench when: (1) tough-alloy steels require maximum hardness via fast cooling, (2) part geometry is simple/uniform with low distortion sensitivity, (3) through-hardening or case-hardening with target hardness driving the choice. Select Iloquench 21 delayed-quench when: (1) thin-section or complex-geometry parts where fast cooling causes excessive distortion, (2) lower-alloy steels where slower cooling still achieves target hardness, (3) distortion-budget is the primary constraint. For uncertain cases, our technical team will analyse your specific alloy + part geometry.
Iloquench M martempering bath temperature: 150-200°C, depending on alloy steel Ms (martensite-start) temperature. The bath is held just above Ms to allow the part to equalise temperature before further cooling, dramatically reducing distortion vs conventional through-quench. Higher-Ms steels (lower-alloy) use lower bath temperature (150-160°C); higher-alloy steels with lower Ms use higher bath temperature (180-200°C). Cross-reference the specific alloy CCT diagram.
Quench-oil oxidation life is tracked via TAN (Total Acid Number — rising trend signals oxidation), viscosity drift (rising = oxidation, falling = thermal cracking), water content (>0.05% degrades performance), and cooling-curve drift (Wolfson re-test every 12-18 months). Vasundhara Specialities provides quench-oil sample analysis as part of the supply relationship — typical analysis interval 6 months for production-volume HT shops, 12 months for low-volume shops. Drain decision is condition-based, not calendar-based.
Vacuum-furnace heat-treatment requires very low oil vapour pressure to minimise vacuum-pump loading and avoid contaminating the vacuum chamber. Iloquench 25's vapour pressure (≤0.1 mbar at 50°C) is approximately 5-10× lower than Iloquench 1, dramatically reducing vacuum-pump duty. Additionally, Iloquench 25 produces lower oxidation products during the quench cycle, leaving cleaner part surfaces — critical for aerospace + medical-grade components.
Production heat-treatment service with proper filtration (continuous 25-micron filtration), water-removal (centrifuge or coalescer), and stable bath-temperature management: Iloquench 1 service life typically 24-36 months. Sample analysis (TAN trend, viscosity, cooling-curve drift) drives drain timing — top-up only when properties drift outside specification. Calendar-based replacement is rarely necessary.
Iloquench 25 vacuum-furnace grade meets aerospace AMS 3025 specification for vacuum-furnace quench-oil service. Iloquench 1 + Iloquench 21 meet typical commercial heat-treatment specifications (Wolfson cooling-curve benchmark, IFHTSE category). For specific AMS / aerospace specification compliance, per-batch certification provided on enquiry. Customer base includes HAL Hyderabad, BDL, MIDHANI for AMS-grade quench service.
Production heat-treatment shops typically maintain 1-2 drums Iloquench in immediate stock + 4-6 drums in reserve for the quench-bath top-up cycle. Vasundhara Specialities provides 48-72 hour replenishment dispatch from Hyderabad to South-Indian HT shops, with emergency-response 24-48 hour for unscheduled quench-bath replacement events. Direct WhatsApp business-line for HT-shop dispatch coordination.
