Steel Blue puts you in charge of a precision bluing workshop for knife and
spring steel. Every order lists a steel grade and a required temper color,
and your timing decides the payout.
Master five hands-on stages:
- HEAT: lock the furnace inside the green Ac3 band.
- QUENCH: plunge into oil at the perfect moment. Too early cracks the blade,
too late leaves it soft.
- TEMPER: stop the sweeping needle on straw, purple or blue as ordered.
- BLUE BATH: hold concentration and temperature in the green zone while the
magnetite film forms.
- SEAL CHECK: catch the scanner on the sample spot to verify the oil seal.
Earn coins from hardness and color accuracy, then install permanent workshop
upgrades: an infrared pyrometer, quench oil circulator, temper color
comparator, bath auto-doser, hot air sealer and lucrative military contracts.
Original art, synthesized sound effects and full offline play.
