Do you provide Ultrasonic testing according to EN 10228-4 before Annealing? Can you provide us chemical composition with all residual elements? What is the hot working Ratio? What is the ramp up velocity of the furnace? What is the temperature of the forgings when it was introduced in...

Thermocalc Software is a powerful thermodynamics software, but it makes computation at equilium , who can you expect to use it to predict CCT & TTT diagrams ?

Thanks Ed Stainless "....is that you have to re-balance the chemistry for each C level...." Do you mean balance between Gammagenic and alphagenes elements ?

Many thanks to all people ! I am looking for a figure with can shows effect of the carbon of mechanical Ph properties of 17-4 PH alloy Thanks in advance

I really appreciate your advice Thanks redpicker

The ASME SA 705 code state's that : C% content in 17-4Ph Stainless Steels is 0.070 % Why we can not go above 0.070 ? Is it related to intergranular corrosion ? Is it related to retained austenite ? Is it related to hot working ? Is it related to Impact Charpy Toughness ? Any Help Thanks

May be a basic question but an internal auditor ask us a question: Hardness testing Is it a NDT Test? I really don't have the good answer For rough forgings parts I guess it's NDT TEST, for machined parts I guess NO Any help? Thanks

salmon2 : Great answer ! thank you for your contribution

• What do you mean by small amount? • What kind of grades? • Who is the end user Market? Critical or nor Stainless Steel Nuclear or power part is different form basic part? • Is there any specification provided by your customers? Stan

Hi Guys I ma looking for the maximum tool steels admitted in Commercial Hot Tool steels grades like H11 & H13 A supplier n°1 sends us a Quotation for H11 hot work Steel with 0.024 %of phosphorus. A second supplier sends us a quotation with 0.018 % phosphorus but with higher price The...

Hi gafoorkti Look at this : " Martensitic and Precipitation Hardenable Stainless Steels All Martensitic and most precipitation Hardenable stainless steels are ferromagnetic. Due to the stresses induced by the hardening transformation, these grades exhibit permanent magnetic properties if...

gdous314 I agree with metenger you must purchase this wonderful (book or Cd-Rom) : stahlschluessel http://www.stahlschluessel.de/en/handbook.html it's a "bible" for steels standards Stan

arunmrao Dear Friend Anyway if they don't hire you. They have lost a HUGE Metallurgical experience. For me : you are a GREAT Metallurgist Respect ! Ps : ultra high strength steels is dedicated mainly to Aerospace grades : ATI, Carpenter,Aubert & Duval, Tata Steels(Former Corus...

Hi everybody I have an ingot (316L) with a high amount of lead "19 ppm" What is the impact of the amount of lead on: The hot working? Mechanical properties? Corrosion resistance? I don't read any thing any in internationals Standard ! What is the maximum amount permitted in stainless...

Great answer redpickler ! Respects
