What is material equivalent?
Two propositions are materially equivalent if and only if they have the same truth value for every assignment of truth values to the atomic propositions. That is, they have the same truth values on every row of a truth table.
What is 18CrNiMo7 6?
18CrNiMo7-6 grade steel is an alloyed case hardening steel for heavy and high strained gear parts with high demands on toughness at core. It has tensile strength of 1050 – 1350 N/mm².
What is 17CrNiMo6?
17CrNiMo6/1.65827 Alloy Steel is is a heat treatable, low alloy steel containing nickel, chromium and molybdenum as per DIN Germany standard which is known for its toughness and capability of developing high strength in the heat treated condition while retaining good fatigue strength.
What does equivalent standard mean?
Equivalent standards means those standards adopted by the Board intended to be used as alternative equivalents to determine competency for education, training and testing for licensing architects and/or landscape architects and registering interior designers and for complying with the Post-Military Service Occupation.
What is SAE 1045 steel?
AISI 1045 steel is a medium tensile steel supplied in a black hot-rolled or normalized condition. It has a tensile strength of 570 – 700 MPa and Brinell hardness ranging between 170 and 210. AISI 1045 steel lacks suitable alloying elements and hence does not respond to the nitriding process.
What is the equivalent of a HSC?
Tertiary Preparation Certificate
TAFE NSW courses and related support programs will boost your confidence and be an asset for life. Courses include the Tertiary Preparation Certificate (TPC), an alternative to the HSC for university entrance, skills for work and vocational pathways, education support, employment and training.

What kind of steel is 18crnimo7-6 made of?
Alloy steel 18CrNiMo7-6 is a grade consisting of the addition of chromium, nickel, molybdenum and coal with a range characteristic for all carburizing grades. 1.6587 materials, unlike other simple steel grades, can be used for much larger sizes and loads.
What is the maximum hardness of 17nicrmo6-4?
After case hardening and hardening treatments, the surface reaches an elevated hardness. 17NiCrMo6-4 is used for the production of mechanical parts, which are submitted to wear (gears, camshafts, bushings, pinions). Soft Annealing: Heat to 700oC min, cool slowly. This will produce a maximum Brinell hardness of 229.
