HS 188 Solution Treated

Verifiedmetal

HS 188 is a cobalt-based superalloy with tungsten and chromium additions, designed for high-temperature structural applications in gas turbines and aerospace engines requiring sustained performance above 1000°C. Solution-treated condition provides optimal balance of strength and ductility through controlled heat treatment, suitable for sheet applications where creep resistance and thermal fatigue resistance are critical performance requirements.

Regulatory Screening

Environmental

Export Control

RoHS, REACH, and Prop 65 statuses are validated against official substance lists (ECHA SVHC Candidate List, OEHHA Prop 65, RoHS Annex II). Other regulations are estimated from composition and material classification. All screening is a starting point for due diligence — always verify with your supplier before making compliance decisions.
