3004 H14 और 3004 H34 दोनों एल्यूमीनियम मिश्र धातु हैं, लेकिन वे अपने यांत्रिक गुणों और स्वभाव पदनाम के संदर्भ में भिन्न हैं.

NS “एच” मिश्रधातु में पदनाम का अर्थ है “तनाव से कठोर,” जिसका मतलब है कि एल्युमीनियम को ठंड से काम करने या स्ट्रेन हार्डनिंग की प्रक्रिया द्वारा मजबूत किया गया है. के बाद की संख्या “एच” तनाव सख्त होने के स्तर को इंगित करता है, with higher numbers indicating a greater degree of hardening.

3004 is a popular aluminum alloy that contains both manganese and magnesium, which improve its strength and corrosion resistance. दोनों 3004 H14 और 3004 H34 have the same chemical composition, साथ 1.0-1.5% manganese and 0.8-1.3% मैग्नीशियम, but they differ in terms of their temper designation.

3004 H14 aluminum coil is in the annealed or soft state, which means it has been fully strain-hardened to a temper of H14. This results in a relatively low strength but high ductility and good formability. It is typically used in applications that require good formability, such as sheet metal work, कताई, and drawing.

3004 H34 एल्यूमीनियम का तार, on the other hand, has undergone a partial strain hardening process to achieve a temper of H34. This results in higher strength and hardness compared to H14, but with slightly reduced ductility and formability. It is commonly used in applications that require higher strength and better corrosion resistance, such as automotive parts, दबाव वाहिकाओं, and roofing.

In summary, 3004 H14 और 3004 H34 aluminum coils have the same chemical composition but differ in terms of their mechanical properties and temper designation. H14 is in the annealed or soft state, while H34 has undergone partial strain hardening to achieve higher strength and hardness.
