Truck Chassis Steel Grade

Cautions against welding are to prevent the manufacturer from being liable for somebody else s work.

Truck chassis steel grade.

Roll cages depend entirely on what your competition specs are but usually a 350n mm2 yield dom cds tube or 4140 t45 for the higher end. This is a unique opportunity to look at the details and the complexity of the truck construction. Richard toner has spent entire days giving a truck frame seminar for the national truck equipment association. He knows that much about truck frames.

Rusty truck frames can become very unsafe. There are many grades of steel in the marketplace. The heat treated heavy truck frames made at dana corp s parrish frame plant were made from sae 1027m. Made from grade 8 steel these screws can be used in high stress applications such as valves pumps motors and automotive suspension systems.

The typical chemical composition of the material is 0 565c 1 8 si 0 7 mn 0 045 p and 0 045 s. They are at least 25 stronger than medium strength steel screws. Chassis frame rails and liners are cut and formed from high strength steels up to 140 000 ksi. Truck frame rails and chassis components major chassis manufacturers rely on vicon fabricating for formed frame rails.

Our truck frames are fabricated strictly from hi tensile steel. We might be able to help by offering 1 2 thick steel in our grade 100 material for a strong single frame solution. High strength metric class 10 9. Toner president of toner associates pentwater michigan and the ntea s first staff engineer said the frame is the backbone of the truck because it carries the loads we put on trucks.

Chassis rails on heavy duty trucks are usually made from mid strength alloy steel typically with yield strength of 500 750 mpa. We can fabricate new truck frames and even inner or outer reinforcement frames to help get your truck back in shape. The flange distributes pressure over the surface eliminating the need for a washer. Currently the material used for the chassis is a709m grade 345w structural steel which is known as structure steel in simple words with the varying chemical composition leading to changes in names.

The sheet metal work depends entirely on the car in question could be anything from plain old mild stampings and spot welds to high tensile boron alloyed steel with brazed joints. We can assist in calculating the rbm of your truck frame s. Sub frames and attachment brackets are more likely to be made from mild steel yield 250 mpa or a low strength alloy yield 350 mpa so the material strength is probably about half that of the chassis rails. There are at a minimum seven grades of steel that make up the honda ridgeline.
