Q- What is the basic difference between Pipe specification A106 Gr. A / Gr. B/ Gr. C.? (पाइप विशिष्टता A106 Gr. A / Gr. B/ Gr. C के बीच बुनियादी अंतर क्या है )

Answer: – Difference is due to the Carbon content (अंतर कार्बन सामग्री के कारण है)
Percentage of carbon content in (कार्बन सामग्री का प्रतिशत) : –
I. ASTM A106 Gr. A – 0.25 %
II. ASTM A106 Gr. B – 0.30 %
II ASTM A106 Gr. C – 0.35 %

Q- What is the difference between pipe specification (पाइप विशिष्टता में क्या अंतर है) ASTM A312 TP 304 & ASTM A312 TP304L, and ASTM A312 TP 316 & ASTM A312 TP 316L?

Answer: – Difference is due to the Carbon content. The Letter “L” denotes lower percentage of carbon (अंतर कार्बन सामग्री के कारण है, अक्षर “L” कार्बन के निम्न प्रतिशत को दर्शाता है).
Percentage of carbon content in: –
I. ASTM A312 TP 304 – 0.08 %
II. ASTM A312 TP 304L- 0.035%
III. ASTM A312 TP 316 – 0.08 %

Q- What is low alloy steel and high alloy steel (निम्न मिश्र धातु इस्पात और उच्च मिश्र धातु इस्पात क्या है?) ?

Answer – The steel is called a low alloy or high alloy steel depending upon the sum of the percentages of the alloying elements in the steel (स्टील में मिश्र धातु तत्वों के प्रतिशत के योग के आधार पर स्टील को निम्न मिश्र धातु या उच्च मिश्र धातु इस्पात कहा जाता है)

Steel is called low alloy steel if the sum of the total alloying elements is < 5% And if the sum of the total alloying elements is > 5%, it is called a high alloy steel (यदि कुल मिश्रधातु तत्वों का योग <5% है, तो स्टील को निम्न मिश्रधातु इस्पात कहा जाता है और यदि कुल मिश्रधातु तत्वों का योग>5% है, तो इसे उच्च मिश्रधातु इस्पात कहा जाता है।)
