En Series Steel Bars

Product Details:

• BS970: 1955 EN1A, BS970/PD970: 1970 onwards 230M07.
• Related European grades: 9SMn28, BS En 11SMn30
• Werkstoff no. 1.0715
• US Grades SAE (AISI) 1213, 1215.
• EN1A is also available as leaded (EN1A Pb) for enhanced machinability (see our machinability guide)
• Usually supplied the untreated and cold finished (cold drawn or centreless turned) condition. EN1A is widely used for the manufacture of components requiring superior surface finish with high production rates.
• EN1A is a very popular grade of low carbon-manganese freecutting steel, which is most suitable for the manufacture of repetition turned components, such as nuts, bolts, hydraulic fittings and studs, particularly where intricate drilling and machining operations are involved. It can be case-hardened, producing components with enhanced wear resistance.

Product Details:

• In a furnace
• By resistance heating mats
• By induction heating coils
• By suitably disposed gas torches.

Check temperature by means of temperature indicating crayons or paints or by thermocouples used a short distance away from the part that is being heated; a typical distance would be 4 x the component thickness.

Maintain preheat during welding.

• For MMA (SMAW) welding, use basic coated electrodes, e.g. AWS E7016 or E7018, preferably vacuum packed, or dried at the temperature and time recommended by the electrode manufacturer to give a weld metal hydrogen content below 5ml/100g. MIG/MAG (GMAW) welding or flux cored arc welding can also be used with consumables giving weld metal of appropriate strength.
• When welding is completed allow components to cool to 150°C before tempering.
• Heat to 620 - 650°C at a maximum heating rate of 100°C/hr or 6000/thickness (mm) °C/hr, whichever is the lower. Temper for 2 hours. Cool to 200°C at controlled cooling rate of 100°C/hr maximum. Cool to room temperature in still air. In very highly restrained conditions, it may be necessary to consider an intermediate, lower temperature stress relief treatment.
• If it is not convenient to hold the component at an intermediate temperature after welding, pending heating for tempering, the following alternative procedures can be applied. However, if restraint is very high the alternative procedure may not prevent the occurrence of hydrogen induced cracking.

Alternative procedure:

• Boost preheat to 250°C and hold for at least 4hrs.
• Cool to room temperature at a maximum rate of 50°C/hr.
• Temper when convenient.
• Machine component to finished size
• Inspect by dye penetrant, magnetic particle or ultrasonic examination
• Repair any defects. The precise procedure necessary for repair of defects will depend on their position and extent. For example if they can be repaired without causing a hardened heat affected zone a tempering treatment will not be necessary
• The preheating temperature in clause 1 may be reduced by 50 - 75°C if austenitic stainless steel or nickel based electrodes are used. Nickel based consumables have the advantage that their coefficient of thermal expansion more closely matches that of the ferritic steel, thus reducing the risk of cracking in highly restrained situations.
• Suitable electrodes are: AWS E308Mo; AWS E309 (23.12.L to BS EN ISO 3581: 2012); AWS E312 (29.9 to BS EN ISO 3581: 2012); AWS A5.11 ENiCrFe-3; AWS A5.11 ENiCrMo-3.

When stainless steel or nickel based electrodes are used the intermediate heat treatments recommended in clauses 3 and 5 are not necessary unless restraint is very high. Cooling to room temperature after welding can be carried out but tempering will be required if a brittle heat affected zone is unsuitable for service conditions.
