NOTES:
1. 1 MPa = 1N/mm2
2. Minimum tensile strength for qualities HR1, HR2, HR3 and HR4 would normally be expected to be 270 MPa. Where minimum tensile strength is required, the value of 270 MPa may be specified. All tensile strength values are determined to the nearest 10 MPa.
3. The non proportional test piece with a fixed original gauge length (50 mm) up to 6 mm thick sheet can be used in conjunction with a conversion table. In case of dispute, however, only the results obtained on a proportional test piece will be valid for material 3 mm and over in thickness.
4. HR5 grade is for cold rolling only, therefore mechanical properties are not applicable.
5. Where “t” is thickness of steel sheet, in mm.
6. Tensile testing is not mandatory for HR1, unless
agreed to between the purchaser and
manufacturer.
* Properties on mutual agreement between the
purchaser and manufacturer.

NOTES:
1. Steel of these grades can be supplied with the addition of micro-alloying elements like Boron, Titanium, Niobium and Vanadium. The micro-alloying elements shall not exceed 0.008 percent in case of Boron and 0.20 percent in case of other elements.
2. The Nitrogen content of the steel shall not be more than 0.007 percent. For Aluminium killed or Silicon-Aluminium killed, the Nitrogen content shall not exceed 0.012 percent. This has to be ensured by the manufacturer by occasional check analysis.
3. Grade HR4 and HR5 shall be supplied in fully Aluminium killed condition or Aluminium with stabilising elements.
4. When the steel is Aluminium killed, the total Aluminium content shall not be less than 0.02 percent. When the steel is Silicon killed, the Silicon content shall not be less than 0.10 percent. When the steel is Aluminium-Silicon killed, the Silicon content shall not be less than 0.03 percent and total Aluminium content shall not be less than 0.01 percent.
5. When Copper bearing steel is required the Copper content shall be between 0.20 and 0.35 percent. In case of product analysis, the Copper content shall be between 0.17 and 0.38 percent.
6. Restricted chemistry may be mutually agreed to between the purchaser and the supplier.
7. IF denotes Interstitial Free and IF-HS denotes High Strength Interstitial Free.
8. * denotes that dual phase steel may also content Cr and Mo up to 1.0 percent.

NOTES:
1. 1 MPa = 1N/mm2
2.Resistance minimale a la traction pour les qualites HR1, HR2, HR3 et HR4 devraient normalement etre de 270 MPa. Lorsqu'une resistance a la traction minimale est requise, le une valeur de 270 MPa peut etre specifiee. Tout a la traction les valeurs de resistance sont determinees a 10 pres MPa.
3. L'eprouvette non proportionnelle avec un longueur de reference d'origine (50 mm) jusqu'a 6 mm d'epaisseur peut etre utilise avec une table de conversion. En cas de litige, cependant, seuls les resultats obtenu sur une eprouvette proportionnelle sera valide pour materiau de 3 mm et plus d'epaisseur.
4. La nuance HR5 est reservee au laminage a froid, par consequent les proprietes mecaniques ne sont pas applicables.
5. Où «t» est l'epaisseur de la tôle d'acier, en mm.
6. L'essai de traction n'est pas obligatoire pour HR1, sauf convenu entre l'acheteur et le fabricant.
* Proprietes sur accord mutuel entre le acheteur et fabricant.

Aciers inoxydables
L'acier inoxydable est un groupe de chaleur et de
corrosion
resistant aux aciers. Ils ont en general un
resistance a la corrosion dans certains
environnement, ainsi qu'une plus grande resistance a
mise a l'echelle a haute temperature.
L'acier inoxydable est un alliage a base de fer
contenant un
minimum de 10,5% de chrome avec ou sans autre
elements d'alliage. Base sur la teneur en alliage et
la micro structure, les aciers inoxydables sont classes
en trois grandes categories a savoir. Austenitique,
Ferritique et martensitique.
Austenitique
Cette categorie d'acier inoxydable contient 16 a 26% Chrome et 6 a 22% de nickel. ils sont non magnetiques etat recuit et ont une excellente corrosion la resistance. Ils ne sont pas durcissables a la chaleur traitement. Cependant, ils peuvent developper une resistance elevee sur le travail a froid. Ils ont une excellente soudabilite, formabilite, facteur d'hygiene et cryogenique Proprietes. Lors du travail a froid, ils presentent des degres de magnetisme. Ils sont identifies dans le Serie AISI 300.
