A polyamide resin composition for molded articles to be in contact with high-pressure hydrogen, the polyamide resin composition comprising a blend of a polyamide-6 resin (A) and a polyamide resin (B) which has a melting point, as determined by DSC, that is not higher than the temperature which is higher by 20ºC than the melting point of the polyamide-6 resin (A) and which has a crystallization temperature during cooling, as determined by DSC, that is higher than the crystallization temperature during cooling of the polyamide-6 resin (A), the amount of the polyamide resin (B) being 0.01-5 parts by weight per 100 parts by weight of the polyamide-6 resin (A). The polyamide resin composition can give a molded article which, even when high-pressure hydrogen charging and pressure release are repeated, is inhibited from developing flaws and which has excellent weld properties. |
