💡 Low phosphorus and sulfur ensures excellent toughness and weldability for pressure equipment service. Aluminum (≥0.020%) provides grain refinement for improved properties.

Mechanical Properties

TC1 vs TC2 – Quality Levels

💡 Choose TC2 when impact toughness is required – typically specified for low temperature start-up conditions or critical pressure equipment.

Manufacturing Process – Cold Drawing

Cold Drawing Process for Pressure Tubes:

1. Hot rolled tubes are pickled to remove scale

2. Cold drawing precisely reduces the diameter – increases strength

3. Annealing (normalizing) – ensures fine grain structure, restores ductility

4. Straightening – ensures straightness for installation

5. Precision cutting – to exact customer length

6. 100% NDT and hydrostatic testing – guarantees integrity

7. Charpy impact testing (TC2) – verifies low temperature toughness

Elevated Temperature Yield Strength (Rp0.2 MPa min)

💡 P235GH maintains good strength up to 400°C – above this temperature, use 16Mo3 or 13CrMo4-5 alloy grades.

Key Applications

💡 TC2 is recommended for critical applications requiring impact toughness at low temperature start-up conditions.

DIN 17175 Cross-Reference

💡 P235GH is the direct replacement for St35.8 – for legacy projects, we supply both standards.

Ukukhethwa Kwebanga – Isevisi Yezinga Lokushisa Eliphansi

💡 Ibanga 6 liyathandwa ezinhlelweni eziningi – inikeza amandla aphezulu (≥415 MPa tensile) uma iqhathaniswa ne-Grade 1 (≥380 MPa) ezingeni elifanayo lokusebenza.

Ukuhlanganiswa Kwamakhemikhali

📌 Inothi leBanga 1: Ukwehla ngakunye kwe-carbon ngo-0.01% ngaphansi kuka-0.30% kuvumela ukwenyuka kwe-manganese ngo-0.05% ngaphezu kuka-1.06%, kufike emkhawulweni ongu-1.35%.

Izici Zemishini

Izidingo Zomthelela We-Charpy Ekushiseni Okuphansi

💡 Ukuhlolwa kwe-Charpy impact kuyimpoqo kukho kokubili Ibanga 1 neBanga 6 ku- -45°C – umbiko oqinisekisiwe uhambisana nayo yonke imithwalo.

Inqubo Yokukhiqiza – Ukudonsa Okubandayo Nokuqina Ekushiseni Okuphansi

Inqubo Yokudonsa Ebandayo Yesevisi Yezinga Lokushisa Eliphansi:

1. Amashubhu agingqiwe ashisayo ziyacutshungulwa ukuze kususwe amakhasi

2. Ukudonsa okubandayo inciphisa ngokuqondile ububanzi

3. Ukwelashwa ngokushisa (ukujwayela noma ukukhulula ingcindezi) – kuqinisekisa ukwakheka kwezinhlayiya ezinhle ukuze kube nokuqina ekushiseni okuphansi

4. Ukuqondisa – iqinisekisa ukungaguquguquki kobukhulu

5. Ukusika ngokunemba – ukuze kube ubude obunembile

6. Ukuhlolwa kwe-NDT nokuhlolwa kwe-hydrostatic okungu-100% – liqinisekisa ubuqotho

7. Ukuhlolwa kwe-Charpy impact ku- -45°C – iqinisekisa ukuqina ekushiseni okuphansi

Ukuqhathanisa Izinga – Izinga 1 nezinga 6

💡 Ibanga 6 linikeza amandla okudonsa aphakeme ngo-17% kune-Grade 1 – ikhethwa kakhulu ezinhlelweni eziningi zamazinga okushisa aphansi lapho amandla aphezulu ewusizo.

Izicelo Eziyinhloko – Inkonzo Yamazinga Aphansi Okushisa

💡 Ibanga 6 liyona ndlela ekhethwayo ezinhlelweni eziningi zokushintshana ukushisa emazingeni okushisa aphansi ngenxa yamandla ayo aphezulu nokutholakala kwayo okubanzi.
