HSS material
HSS is a common term for steel within certain strength parameters (high strength steel).
HSS stands for H igh S trength S teel.
The vehicles are constructed from a number of different steels, partly to obtain an optimized body (collision safety, rigidity, fuel economy, etc.) and partly to make them as easy to repair as possible.
The steels are divided into four groups according to their tensile yield stress, that is to say the force that is necessary to bring about plastic deformation of the material
These groups are
MS - M ild S teel. Trade steel with a highest tensile yield limit of 220 Mpa.
HS - H igh strength S teel. Steel with a yield point of 220 - 450 MPa.
EHS - E xtra H igh strength S teel. Steel with a yield point of 450 - 800 MPa.
UHS - U ltra H igh strength S teel. Steel with a yield point of 800 - 1400 MPa.
Soft Steel
This material is sometimes called commercial steel. This group of steels accounts for the highest proportion (50-60%) of the materials from which the car is made and it is used where the need for a stronger steel cannot be justified.
High-strength Steel
This group consists of three main types of steel
- Phosphorus-alloy steel which gets some of its increased strength from the alloying constituent phosphorus.
- HSLA steel ( H igh S trength L ow A lloy). This is a low-alloy steel which obtains some of its increased strength from the alloying constituents Vanadium, Niobium or Titanium.
- DP steel ( D ual P hase). This steel gets its increased strength from the heat treatment it is given during manufacture. This is where a dual phase structure of ferrite (iron) and martensite (carbon) is formed. This steel loses its strength if exposed to temperatures above 300°C.
Extra High-strength Steel
This group includes both HSLA and DP steel but their strength is further increased with larger proportions of alloying constituents.
Ultra High-strength Steel
This group consists of two main types of steel.
DP steel. Here the strength has been successfully increased through an advanced manufacturing process and a higher proportion of alloying constituents.
BORON steel/Material
The strength of this material is obtained through the addition of the element Boron and also its comparatively large carbon content. The sheet metal sections are formed in the incandescent phase between punch and die where hardening of the material also takes place.
HSS steel
HSS-steel (HSS = High Strength Steel) has a higher yield point and ultimate tensile strength than ordinary sheet steel.
The yield point of the material increases with heat treatment.
HSS steel may therefore be more difficult to straighten than ordinary sheet steel.
- All welding work should be carried out in accordance with this manual.
Note. "Heat-straightening" of the sheet steel, such as in an alignment bench, must not be performed.
When an alignment bench is used, HSS components may prove troublesome if the counterstay is not correctly positioned so that the maximum power of the puller is used.
It is therefore necessary to pay attention to the way the body reacts to the puller and make sure that only the deformed area moves.
All body parts are made of HSS.
The grey areas in the pictures have HSS with a yield point above 340 N/mm2 and extra care must therefore be taken when repairs are carried out.
Scheme 165
Scheme 166
Scheme 167
The parts marked black are made of BORON steel. BORON steel has an extremely high yield point and ultimate tensile strength. When replacing BORON steel body parts the spot welds cannot be drilled out and grinding or plasma cutting is used instead. BORON steel exhibits good weldability.
Galvanizing is not possible in the manufacture of BORON steel. It is therefore extremely important to treat these parts with corrosion inhibitor.
Note. BORON steel does not lend itself well to straightening.
Note. Making joints in BORON steel is allowed where the method employed indicates this. Prepare accurate templates and use a cutting wheel or plasma cutting equipment.
Note. BORON steel must not be heated
Note. Protect interior equipment and glass when grinding or plasma cutting.
