Steel propertiesdependson chemicalcomposition andheat treatmentstabilize austenitic structure. Nickel (Ni) is acommon alloying element in stainless steels andis added for stabilizing the austenitic structure.Materials selectionProper materials selection is vital for the lifetimeof the steel. Knowledge about exposure to internalor external corrosive media is a key considerationin making the correct choices. Temperature, pressure, concentration of corrosive media, flow rate,design and physical connection to other materialsare also of crucial importance.Corrosion resistanceBut corrosion resistance is not the only thingIn general terms, steel is said to be stainless whenchromium content is above 10.5 %.

Mechanical propertiesof stainless steel alloysDuplex stainless steels like S8490 (“duplex”)and S8492 (“super duplex”) have excellentcorrosion resistance combined with high strength,due to their fine grained two-phase structure.Mechanical properties are a consequenceof material structure and are determinedMartensitic stainless steels like S134M andby the type and amount of alloying elementsS165M are tough even though they have beenand subsequent heat treatment. Stainless steelhardened to a high tensile strength of 800-1,000alloys may be grouped into hardenableMPa.

Higher temperatureand duplex) structures.increases toughness and decreases strength,and vice versa. SSA will be pleased to help youAustenitic stainless steels like SSA gradesfind the optimal properties for your application.S316L / S128MIIIsuper have low yield strength,although their hardness and strength can beincreased by adding Cr and Mo (6Mo steel).Austenitic steels are very ductile and tough(impact test at -196 C) and are non-magnetic.89

Welding causes a localNormalising is a heat treatment performedon carbon-manganese steel by heating to about900 C and cooling in air. The micro structureis named ferrite-perlite. Stress-relieving at about600 ºC for reducing stress after welding to casttemperature rise close to the weld, which resultsin localised expansion followed by shrinkageas the metal cools. This can cause the steelto deform or cracks to appear due to localisedstresses. Stress relieving evens and reducessteel will not affect the structure of normalizedthis stress. It also reduces hardness in thesteel, but will temper hard zones (HAZ) aroundheat-affected zones in the base material closethe weld deposit.to the weld deposit, creating a tougherweld connection.Quenched and tempered (QT) describesa two-step heat treatment process: first heatingAging is also known as precipitation hardening.to about 900 ºC and then fast-cooling in wateror polymer emulsion. The next step is the tempering, with the temperature depending on the steelgrade and the specification of hardness/strengthand toughness. In general terms, low temperatureis used to achieve high strength and low toughness,and vice versa. High alloyed hardenable steel maybe allowed to cool in oil or air to harden.For some stainless steel grades (e.g. 17-4 PH)and some Nickel base alloys (Alloy 718) agingby heat treatment is required. This is a two-stepprocess were the alloy is firstly solution annealedfollowed by rapid cooling, and then held at anelevated temperature for some time to producefine dispersed precipitates (particles that increasesstrength).Solution annealing describes a heat treatment1011
Below, you will find some steel alloys groupedby structure:Carbon steel grades as well as martensiticstainless steel grades are quenched andtempered (QT), gaining a tempered martensiticstructure. The mechanical properties aredepending on the tempering temperature level.Low tempering temperatures result in highstrength/hardness but less ductility andtoughness. On the other hand, high temperingtemperatures result in less strength/hardness butincreased ductility and toughness. (ToughnessHeat treatment arrangedby micro structureis measured by Charpy-V impact testing in Jouleat a specified temperature).SSA supply a range of different stainless steelalloys. Most of these alloy steels require veryspecific and carefully managed heat treatment toobtain the required quality and material structure.SSA has extensive capacity for isothermalannealing, normalising, stress relieving, hardening, quenching and tempering of steelproducts.

Cast or forged steelManufacturing steel is a lengthy process.It begins at the melting shop, where steel meltsare produced in electrical furnaces, and finishingrefining and alloying process in an AOD converter(AOD Argon Oxygen Decarburisation).Steel alloys intended for forging are first castinto ingots. In the forging plant, ingots are heatedto make them ductile for hot forging.If the product is too complex for forging, castingmay be an alternative.Forged steel products are normally more fine-grained compared with cast steel. This may bereflected in the improved mechanical propertiesof forged steel.Due to the different requirements that apply tothe mechanical properties, cast and forged steelneed to meet separate steel 8614071428144914691490C̊EmptyTemperatureY1819

WeldabilityTo calculate the preheat temperature, the weldingengineer needs to know the expected heat inputIn specific terms the weldability of carbon-(Q) calculated from the formulae:manganese steel grades, the CE factor used inpreheat calculations contains chemical elementsincreasing the hardenability of the steel:CE %C %Mn6 %Cr Mo %v5 %Ni %Cu15Q U·I·ĸv · 1000U voltage, I electric current,v welding speed (mm/s) andĸ welding factor (efficiency).Preheat temperature is defined as the localisedtemperature of the base material at the pointwhere you start welding. After a few weld passes,the steel will be hot, and we may have to waitfor the temperature to decrease to the maximuminter-pass temperature before proceeding.In addition, it is necessary to consider localisedhydrogen content (moisture, oil, grease, dust)as well as the thickness of the steel.Welding procedure approval starts by makinga pWPS (preliminary welding procedurePreheating is performed to control the hardnessspecification) for the welding test.in the HAZ (Heat Affected Zone).Excessive hardness may cause reduced ductilityand toughness, or even hydrogen cracks.The welding parameters are logged duringthe welding sequence.
