HeatTreat Bench

Austenitize, quench, cryo, temper — step by step, with a source on every line. Pick a target hardness and the temper updates. Built for the shop, not the showroom.

HeatTreat Bench is a metallurgy reference and shop log for anyone hardening steel: knife and tool makers, blacksmiths, and machinists who want the numbers right and want to know where they came from.

THE WHOLE CYCLE, STEP BY STEP Normalize, austenitize, quench, cryo, and a double temper — laid out as a vertical timeline with the temperature, the soak time, and what to watch for at each step. A temperature-versus-time curve sits above it so you can see at a glance where you are and what comes next.

PICK YOUR HARDNESS Choose a target Rockwell and the temper temperature updates to match, with the hardness that schedule actually produces for that alloy.

A SOURCE ON EVERY LINE Supplier datasheets disagree with each other, and metallurgists will tell you plainly that some are wrong. Every schedule in HeatTreat Bench cites its source, and the data is versioned — so you always know what you fired with and can judge it for yourself.

SOAK TIMERS THAT WORK IN GLOVES A big, high-contrast countdown for austenitize soaks. Readable across the shop, usable with gloves on.

RECORD EVERY HEAT Log the actual temperatures, the quench you used, the hardness you measured, and what went right or wrong. Tied to the steel, so the schedule that worked is the one you repeat.

WORKS AT THE FURNACE The steel library lives on-device. No signal in the shop is not a problem.

SAFETY AND ACCURACY Heat treatment involves extreme temperatures, hot quench oil, and cryogenic fluids. HeatTreat Bench gives guidance, not guarantees: alloy behaviour varies by supplier, batch, and equipment. Verify every value and test hardness on your own coupons. You are responsible for safe operation of your own equipment.
