RE: Minimum temperature range for common low carbon steels. The ductile to brittle transition temperature can vary considerably for low carbon steels, and is dependent on grain size, heat treatment and alloy content. The fracture appearance transition temperature for 50% flat fracture (FATT @ 50%) is a good reference point for comparing materials.
In Texas, you need a score of 70 to pass each exam. But, each exam consists of two parts â the ânationalâ insurance section and the âstate rulesâ section. The national and state questions are mixed together in Texas. You will need a combined score of 70 to pass.
Meet the minimum age requirement. You must be at least 15 years and six months old in order to qualify for any driving privileges in Arizona. At that age, you can earn a learner's permit.
