BODY CONSTRUCTION CHARACTERISTICS
Definitions of Steels used in the Jeep Compass:
MS 66 - Represents an uncoated Hot Rolled Steel Sheet used mainly for interior braces and reinforcements.
MS
67 - Represents an uncoated Cold Rolled Sheet structural steel used in areas where structural integrity is critical.
EG., the type of steel used for the “A” pillar
.
MS
264 -
Represents an uncoated high strength low alloy (HSLA) steel used in applications where structural integrity is critical.
MS 6000-44A - Low carbon, hot dipped galvanneal (or EGA) with 45 g/m² minimum coating weight on both sides.
- Most common Sheet Steel product used by Chrysler.
MS 6000-44VA - 50 ksi min. yield strength, HSLA, killed steel, with 44 g/m² minimum coating weight on both sides.
- Most common high strength coated steel product used by Chrysler.
MS 10176 - Boron-alloyed steels ate analogy with 22MnB5 which are matched to the hardening process die. Sheet
blanks are heat treated in the furnace on an inert gas or air atmosphere and then formed in the press die and hard-
ened at the same time. The boron is produced in two configurations one for use in upper body and one that has hot-
dip aluminizated coating for corrosion protection.
MS82-1228 - Represent a coated high strength low alloy (HSLA) hot or cold rolled sheet steel used in applictions where structural
integrity is critical.
