Traternit Tratamento Termico

What Traternit Tratamento Termico does

Traternit Tratamento Termico Ltda is a privately held Brazilian industrial services company founded in April 2002 and headquartered in Diadema, São Paulo. The company delivers commercial heat treatment services to industrial customers, with a service portfolio spanning black oxidation (oxidação preta), nitriding (in both liquid and gaseous forms), general tempering, austempering, induction heating, and vacuum hardening. Operations are conducted from a single facility that combines production, office, and an in-house metallurgical laboratory equipped with Brinell, Rockwell, Vickers, and micro-hardness testers, metallographic cutting and polishing equipment, layer thickness measurement, and a 1,000 kg digital scale. The company is ISO 9001:2015 certified and operates under a Sociedade Limitada (Ltda.) structure directed by José Carlos and Sandra.

The firm serves five principal industrial verticals: auto parts (auto-peças, the primary segment), precision machining (usinagem), tool and die shops (ferramentarias), metal stamping (estamparias), and plastics processing. Its go-to-market is direct B2B sales, with customers requesting quotes via phone or a website form ('Solicite Orçamento'). Pricing is per-job and quote-based, with no publicly disclosed rates, no subscription or recurring contracts, and no publicly named customer logos. The company has no disclosed funding, no parent company, no subsidiaries, and no geographic footprint beyond Southeast Brazil.

Since founding, Traternit has incrementally expanded its service menu, adding tempering four months after launch and reintroducing liquid nitriding approximately 2.5 years later in response to customer demand. The company functions as a family-operated job shop with a flat organizational structure (5 employees) and has maintained operational continuity for over 20 years without documented acquisitions, mergers, or major capital events.
