S & P Heat Treating Inc operates from 16 Dewey Ave in Warwick, Rhode Island, delivering metallurgical heat treatment solutions to manufacturers and tool shops across the region. The facility runs Monday through Friday from 5:30 AM to 3 PM, closing early on weekends. Owned and managed by degreed metallurgists with three decades of hands-on experience, the company has earned ISO 9001:2015 accreditation through the ANSI-ASQ National Accreditation Board. All seven client reviews on file award the full five stars, reflecting consistent quality and turnaround performance. The business serves customers in Warwick, Providence, and surrounding Rhode Island communities.
What separates S & P Heat Treating from typical metal shops is their validated process portfolio. They handle specialized procedures including age hardening, case hardening, carbonitriding, and thru-hardening tempering, each metallurgically proven before implementation. Their black oxide coating service delivers corrosion resistance and a factory-fresh appearance for restored components. The company maintains approvals from major industrial clients including Navy, Ford, and GM, plus nuclear sector certifications , credentials that speak to their precision and documentation standards. Every job receives on-time delivery and competitive pricing, backed by metallurgical expertise rather than guesswork.
Client feedback highlights specific team members and scenarios. Mike and his staff earn recognition for accommodating rush orders with impressive turnaround , one reviewer restoring a vintage item needed black oxide dipping and received it faster than anticipated. Another customer working with H&S Tool and Engineering describes S&P as an indispensable part of their team over multi-year relationship. The technicians explain job specifications clearly and recommend appropriate treatments rather than upselling unnecessary procedures.

Services
Metal Hardening
Increases surface wear resistance by heating and quenching to transform metallurgical structure.
Thru-Hardening Tempering
Treats entire cross-section uniformly rather than surface-only, ensuring consistent hardness throughout.
Metal Annealing
Softens metal through controlled heating and slow cooling, relieving internal stresses and improving machinability.
Case Hardening
Creates a hardened surface layer while maintaining a tough ductile core, ideal for gears and wear components.
Carbonitriding
Adds carbon and nitrogen to steel surface simultaneously, enhancing hardness and fatigue resistance beyond standard case hardening.
Age Hardening
Precipitation-hardening treatment that increases strength over time through controlled aging phases.
Black Oxide Coating
Delivers corrosion-resistant black finish while preserving fine dimensions, suitable for restored parts and tooling.
Stress Relieving Metal
Reduces residual stresses from welding or machining without significantly altering mechanical properties.
